[FULL] Brother-in-law wants to steal my wife from me, but his wife found out!

Brother-in-law confessed to my wife that she is the love of his life and thought he could steal her from me. But his plan backfired when my sister found out. Yesterday, my brother-in-law, out of the blue, asked my wife if she could meet him for lunch. There's something he needs to talk to her about. My wife tells me about it before accepting and asks if it might have something to do with my sister. Maybe they are having problems and he wants to discuss with another So she accepts and they meet for lunch at a place near her office the next day. That's where he tells her that he is in love with her. He lays it on thick. How beautiful she is, how she makes him feel, how he would treat her if she were his, how it was love at first sight. Mind you, this man is married to my sister and has two kids. He and my wife had a friendly relationship. Our family sees each other often as we're a close family. He does text her frequently, but there was nothing overly forward. My brother-in-law texts and calls my mom too, so none of us thought anything of it. I want to stop a moment and emphasize that my wife isn't cheating on me with him. My wife and I share an iPad and I see every one of her texts from there. We are also looking at each other's phones all the time, so none of that is going on. So she doesn't let him finish, walks out, and calls me immediately to tell me what happened. While she's on the phone with me, the texts from him start. He didn't mean it, he thinks it's only infatuation, blah blah blah. She leaves work early to come home to talk to me about this and her phone is blowing up the entire time with calls and texts from him. I tell her to answer and so she put him on speaker so I could hear. He's crying, begging not to tell my sister. Apparently, when we were together this past weekend, he thought that she was flirting with him and that he thought they had a moment when they were alone in our kitchen. Now, my wife is a major ball buster and I suppose I can see how that can be taken as flirting. He asks if she told me, to which I answer yes, as I'm on speaker. Surprise. Then, he starts begging me. This went on a while. My main question was whether he had cheated on my sister before. He said no, swore on his kids' lives. It's just my wife. He said I should understand. So, I'm done listening at that point and told him I wasn't going to do anything tonight and I would call him tomorrow. That's where we are right now and I really don't know what to do. My wife says drive over there right now and tell my sister but the idea of wrecking my sister's family is killing me. Thinking about what it will do to my nieces makes me want to vomit. I know the right thing to do is tell my sister but I'm also thinking about my wife as well. Even if my sister doesn't divorce him and they reconcile, I can't see how we are ever together again like we were before, if at all. This whole episode can tear my family apart. I don't know what to do. Any advice will help. A little after 12 last night, I got a call from my sister and says that she has to tell me that my wife tried to begin an affair with her Well, well, well. He tried to pin it on her. I told her that's not the case and I will be right over. So, I get on the phone, wake my mother and father, tell them what's going on, wake my younger brother, tell him. My mom and dad head to my sister's to sit with their kids and my brother comes to our house to sit with ours as my wife and I head over. My sister is out on the front porch with my brother He looks beaten. He knows we have texts, messages, and voicemail. I don't really know what he was hoping to accomplish. My wife gives my sister her phone. She sees the text, listens to the voicemails and he starts sobbing. Before she can say anything, my brother-in-law is a firefighter, a big tough guy so this is a scene. My sister is pretty tough. She tells him to stop it, pack a bag, and go. She can't stand to look at him. There's more begging but she has no patience for it. So, my sister walks off to talk to my wife. I see them hugging so at least I feel like they're okay. They've actually been friends since college. I met my wife through my sister so they are really tight. The thought of this wrecking her friendship had been weighing on me. This leaves me with my brother-in-law. He is broken so I feel more sympathy than anger. He says he's sorry. He just couldn't help it. It's not hard to fall in love with my wife so I get it but damn man. He eventually picks himself up and leaves. So, we are all there all night. My sister starts asking my wife why her husband would think any of this would work out. He had to have some reason to believe that she felt the same way. My sister says they hadn't been having problems. Everything was as it had always been. My wife is crying at this point. She gives my sister her phone again and they read every text ever sent over the past two years. Nothing there. My wife was just herself. She has a playful personality and so does my brother-in-law so they tease each other. She does the same to my mom and younger brother as well. The only thing she could think of was the moment in the kitchen this past weekend. He referenced they both went for the fridge at the same time and they playfully jostled for who would get there first. He let her win but he reached around her waist to get a beer slowly and she did feel the way that he did it was a little inappropriate. She says she should have called him on it but didn't want to make it a big thing. So then, my sister starts going through his macbook to see what else she doesn't know about. She's angry and frantic at this point. She guesses the password, starts searching and finds a lot of pictures of my wife on that computer. They went back years and always isolated on just her. What in the love actually was this? We had gone as couples to the Caribbean a few years earlier. My wife wore a bikini. She usually doesn't but since it was adult only, she did. There were probably 50 pictures of her in that bathing suit so he's been secretly snapping these for years. This has become creepy now. Unfortunately, the mess continues. My sister agreed to talk to her husband last night and let him explain. She puts my wife on FaceTime during this conversation so there will be no lying. I'm listening in as well off camera. My sister is also recording the whole thing. He admits he's been obsessed with my wife for years. It started the day he met her. My wife and I were dating at that time but he met my wife before he met me. Like I said, my wife and sister are longtime friends and my sister wanted to introduce her boyfriend to her friends. He thought it was only physical for a while but over time he knew it was more. My sister nearly kicks him right out there but listens a little more. She eventually asks what made him think that my wife will leave me for him. He answers that there is obviously mutual attraction and he figured it would begin as an affair and then things would progress from there. My wife and sister exploded at that point. A lot of cursing, a lot of screaming. The phone call is over. My wife hangs up because at this point she's concerned for me. She's shaken and distraught, assures me the attraction was one-sided. I never thought it wasn't. Early on in our relationship, she caught me admiring her as she was dressing, asking if I liked what I saw before her face turned cold and told me never to mess up or I'd never see it again. She meant it. She's serious about trust. Anyway, I knew my brother-in-law was a little cocky but my god, I never knew he thought that highly of himself to be able to pull off something like this. My sister is contacting the lawyer to see what steps she can take to limit his exposure to her kids. My brother-in-law returned home yesterday but she can't legally stop him. They are done. I think he realizes that now. The lawyer tells my sister that since my brother-in-law's behavior over the past few days has been documented, there is a good chance she will be granted full custody. He doesn't seem to even want to fight her on that. My sister will be fine. Any love she had for him is gone and she doesn't seem too broken up about it. The kids don't know what happened yet but my brother-in-law was never around much anyway when their kids were home. It is certain to be hard on them once they know what's going to happen. Many commenters have said that there must be more women but as far as we can tell, there hasn't been. It's just really the obsession with my wife. She's blocked his phone but on the same night he returned home, he sends my wife an email from an account he just made. It started with an apology but then took a turn. He said he never got to finish at the restaurant that day. Then he went on for paragraphs and paragraphs about all the things he loves about my wife and the desperation he felt that led him to do what he did. He mentioned their mutual attraction again and the tension that he always felt was between them and ended with a rather large section about me. Let's just say I didn't know he had such a low opinion of me. He was quite certain that I was not satisfying my wife properly. Poor guy, misjudged me. Anyway, we sent the email to my sister and it will go to the lawyer. It might be enough to get him removed from the house. Finally, my wife isn't great but she is doing better every day. She does blame herself for being too comfortable around my brother-in-law. She is always careful to set boundaries with other men. In case you haven't figured it out already, my wife is pretty stunning and gets a lot of male attention. She and my sister are cool and there doesn't appear to be any resentment. So that makes me happy. We all will be okay. It'll just take time. Thanks everyone.
