Update : AITA for telling my sister we were strangers after she broke all contact with us

Hi. Thanks a lot to everyone for the support in my post. And to those who reached out for support. I'd been emotionally drained almost after meeting my sister. Like I said I had made my peace, after a lot of hurt and futile hope, that I would never see her again.

She had my number, and I hadn't blocked the new number of hers. I'd thought about it, and received advice to, but I just didn't, it slipped from my mind. She asked me on Tuesday how I was doing, and asked if we could meet on Wednesday, she really wanted me to meet her kids. I was really conflicted, I didn't want to oblige her, but I decided to say yes to at least meet them.

I went to her apartment yesterday and met my niece and nephew. My niece had recently turned 9 and my nephew is 6. They're great kids and I really enjoyed seeing them. I remember feeling a certain way when my sister was introducing me and she told him, that the way he's my niece's younger brother, similarly I'm her younger brother. We talked a bit, and started talking about stories from us growing up. I hadn’t and still haven't said everything's ok between us, but our stories and conversation went smoothly. I learned that after she eloped and got married she had moved in with her husband into his place in a town a few hours away from us. That around 2019 they had had moved to the city we were currently in (according to her she didn't know all this time that I later moved here for work after college too). I told her about what I'd been up to all these years, my college, my job, my girlfriend etc.

After that, the kids were in their room and my sister brought up us all doing something again over the weekend. I told her we werent ok, she can't expect me to forget everything. She said she was sorry that her moving out had nothing to do with me, that she missed me. I was angry at the fact that she had no idea the pain I'd gone through both personally and then having to be the crutch for my parents pain. I told her I didn't believe her that she would've been perfectly fine with never seeing me again if she hadnt gotten divorced, that I could've been dead and she probably wouldnt have broken a sweat upon learning it since she was so blissed out from her domestic life. I know it was ugly, I've never said anything like this but in that moment I just wanted her to feel some kind of hurt of the kind she'd given me. She broke down and said I can hate her if I want but to just not hate her forever, there has to be a limit. I regretted saying what I said when I saw her crying so I just sat next to her and asked about why they'd divorced.

She told me that their life had been going alright the first few years. She said she'd even sent word through a mutual when the kids were born (which either the mutual messed up or my sister did because we never heard about it). She said when covid happened her marriage became hell for her, that it had uncovered a side of her ex she never knew. He became abusive, had disdain for their son, revealed he used to record every single conversation of theirs, had convinced her she was crazy and a bad wife and mother. That she stuck with him because of the kids until she had enough, that a very good neighbor of theirs whom she had become friends with gave her a lot of support and even helped line her up with a job. During all this she even blamed our parents for her sticking with the marriage for so long and for not reaching out. I told her they had literally pleaded with her not to do this, I was there, I was 18 not 8. She said they told her she was dead to them if she ran off with him and so she blamed them for her not being able to leave him. I told her that was insane logic and she just didnt want to talk about them and asked me not to tell them about her. I said yeah her relationship with them is her own.

I also asked her who had given her my address, she begged me not to ask her that, that they hadnt given it easily she'd had to swear secrecy, and cry and convince them that I'd want to see my older sister, so I dropped it.

We had tea and snacks after that she asked me again if I wanted to do anything this weekend since she has the kids or we could do somethimg the weekend after just the two of us, I said I don't know. She was ok with that answer. She was tearful again when I was leaving, we hugged and I hugged the kids goodbye too.

My mind has been a mess since then. I lashed out and everything, but also regret what I said, but then I also try to remember how I had felt back then and then get angry again. It feels so weird knowing that shes now 20 minutes away from me and we can visit whenever. I told my girlfriend about all this, she said she supports me no matter what but in her opinion to consider the weekend plan with a cool mind.

This got long, I apologize but Ive been trying to collect my own thoughts on this and writing this just seemed to help. Thanks for the help.
