[FULL] My infertile, abusive sister wants me as her surrogate

I my golden child sister abused me my whole life. Now I am delighted she can't have children, but she wants me to be her surrogate. I have an older sister, Angela, whom I have never liked. She always had to compete with me, but never in a normal sibling rivalry way. Our entire life, she always seemed resentful of my existence as the spotlight couldn't perpetually shine on her. So she had to step on everything I enjoyed. Per se, if I learned piano, she had to learn piano. If I excelled at a subject, she suddenly became a scholar in it. If I told my mum I had a crush, Angela would be dating that boy in a week. I would always tell my parents when she did this, but I was disregarded because sisters copy each other, and I can't gatekeep what she likes. She always monitored what activities I did and the clothes I wore so she could outdo me. If I wore a flannel, Angela would come to school wearing an all-flannel dress. There was also more praise that followed Angela, even if I took the initiative to begin the activity first. She was praised because she was better. My parents would miss work to attend her dance recitals, going to every single one because the world would stop if they missed it. However, I remember they attended only two of mine because they were stuck at work or were otherwise preoccupied. Angela revelled in this. She would make comments under her breath around our parents. Whenever our parents weren't around, she'd tell me how much she hated me and how I should stop trying because I would always come second to her. She also physically bullied me in school. Angela purposely tripped me, threw things at me, and hit me in the hallways on a nearly daily basis. The school had gotten involved multiple times, threatening Angela with suspension, and my parents fought it every time. My parents repeatedly told the administration that this was a family matter and we were just bickering like normal sisters. She was never once reprimanded by either parent once. Angela was caught impaling a cat on the school fence, and my parents still defended her, saying this was normal teenage behaviour. I often was in trouble as Angela would start crying, saying how she was being targeted by the school when I had antagonised her. After one of these occasions, Angela cut and bruised herself to prove to Dad that I was the aggressor. I became a pariah due to Angela's malicious rumours about me, so it was difficult for me to make friends, and I resorted to only befriending people from other districts. Angela eventually made sure I had nobody by stalking them, befriending them, and telling all my friends lies about how I was favoured by our parents, and that I constantly bullied and belittled her. She even stole boyfriends of mine, doing this by convincing them I was horribly mean and an awful person who copied her every move. Once she catfished me on Myspace for four months, invaded my privacy into sending her nudes, which she proceeded to send to my parents and everyone in school, including teachers. Later on, she told one of the boys I liked that those were actually her pictures, and I had catfished her. The day of my high school graduation, my mum sat me down and told me Angela revealed the horde abuse she'd suffered at my hand, and I was no longer welcome in their home. After moving out the next day, my parents made very few attempts to communicate with me, only the occasional holiday and birthday text. Financial aid was also abruptly ended as soon as I stepped foot on campus. I met my now-husband shortly after this, and we were married within a year. They did not feel inclined to attend my wedding or even congratulate me. I informed my parents when I had my first child eight years ago as an opening, but they have not attempted to contact or meet any of my three children. The best I know of Angela now, from what I've heard, is that she got married to one of the boyfriends she stole from me in high school, and she's been posting about her infertility issues and how she can't offer my parents their first grandbaby. After years of silence, I received a text at eight this morning from my mother saying, Hey, it's me, your mama. We haven't talked in a while, and I surely miss you terribly. I wanted to let you know your sister just had a miscarriage earlier this week. Angie and Justin are struggling a lot right now. Send something a little sweeter way, I'm sure she'd appreciate it. Get back to me. I love you. I hate to say it, but I'm glad she's suffering. I'm glad she doesn't get to be a mother. If she tormented me for years, what would she do to a child, especially a girl? I don't wish death on any baby, but I know in my heart that child would be damaged by her. I'm angry at my parents for expecting me to have any sense of obligation to her. I don't even have any sense of obligation to them. They always believed her and dismissed me. I was always the problem child, and it's strange how my mother can be so warm to me when asking me to do something for my sister. Also, the fact they cared more about my sister's now dead fetus than my actual children, who wonder why they only have one set of grandparents. I feel some sort of guilt for it, but I refuse to offer any condolences to my destructive, narcissistic sister, who has been justified in her bad behavior since birth. Maybe this will change her and help her develop empathy or any type of emotion that isn't hate or vindictiveness. If that happens, I would be more than willing to offer support, but until then I feel nothing but a small inkling of happiness that she's hurt. I decided not to respond to my mother. I blocked both of my parents, and I thought it would end there. Wednesday morning my messenger was being flooded with texts from my relatives. Most of the messages consisted of me being told I needed to answer my mother's calls, and how callous I was being. I proceeded to block all of them as well, except my one cousin with whom I'm still in contact, because she knows what Angela did to me. She said that Angela kept calling me an abusive ingrate because I wouldn't talk to her mom. My mom also said that they needed to start inviting me to family events so I would come around to being a surrogate. She said that it really got weird when Angela mentioned that she wanted to use my husband's sperm so her kids would come out tall and with blue eyes. It is mind-blowing. They even said that they just needed to be around me for a year and then they could cut me off again. Angela also said that I am the only way she can have babies because she doesn't want to raise someone's trash child. Reading those messages made me want to hurl. Do they think my uterus is some fish hatchery that can be bought with some kind words and casserole? It's nice to know Angela is too much of a narcissistic person to adopt though. I'm officially done with every single one of them. If they try to come around me, I will get a restraining order before they can even darken my doorstep.
