Hi reddit, new acc just in case, but this is my first time posting here and im conflicted. I (26F) have this friend (27F) who recently got back together with her ex (29M). We'll call my friend Jane and her ex Shit Head. Jane had been dating Shit Head for about 2 years and they had issues for about the entire time that they were together. Jane would tell me and her other friends how much of a slob he was, how he never cleaned up after himself and how exhausting it was for her to pick up after a grown man. She would talk to him about it but it never got better. Twice I had cleaned their dishes while they were away on vacation just so my friend had one less thing to worry about, and she told me she cried when she got home because I had cleaned more than he had in their entire relationship. Not only that, but everything had to be his way. If we were going out to eat, oh Shit Head wants to go to this great place he knows. If we were going to the beach, oh Shit Head's favorite beach is this one. He comes from a rich family so he didn't have to worry about money, but my friend didn't grow up this way, so she just agreed to whatever he said. From buying themepark passes (she gets motion sickness on rollercoasters) to living with him in an apartment she can't afford, which then lead to her getting into 20 thousand dollars of credit card debt. He said he would take care of her and never did. He belittled her constantly, even infront of her family!! While visiting his family for Christmas, she was so depressed that she was contemplating suicide and was writing up drafts for a suicide note!! After all of that, she still stayed. I tried to support her through all the many fights they had, even while everyone else was telling her to just break up with him already, I told her that if she believes that he can actually change for the better, I will support them. Guess what? That didn't happen. He's a fucking asshole and when they finally broke up it felt like things were gonna change. Jane was saying that she's never gonna date a rich privileged boy ever again, she had filed for bankruptcy and got her debt cleared, but she immediately started dating right after the break up. She dated a couple guys and after a couple months Shit Head had mailed a hand written letter saying how much he missed her but failed to apologize or take any accountability for their relationship failing. This scared her pretty bad and she was freaked out for a while after that. Thank God he's out of her life, right? After a while some guys she dated didn't work out, and she even got ghosted a couple times which hurt her ego. I thought that she was going to take a break from dating so she could realize she didn't need anyone to be happy, but instead she broke some horrible news. A couple weeks ago she told her sister and i that she was seeing Shit Head again!!! I grabbed her by the shoulders and said remember when he promised to change and didn't? She told me that she thinks he really did this time but I just shook my head and moved on. After Jane told us that they were seeing eachother, her sister and I new that they were going to get back together. It was inevitable, but maybe he did change? Fast forward and I saw on her Finnsta (side instagram account our friend group uses to vent or post random shit) she posted "back together with Shit Head and I already feel like killing myself" I immediately texted her to see if she's okay, and to spare you the details, he had assaulted her and gaslit her into thinking it was her fault. I told her that it was not her fault and he's the toxic one for doing that. She told me she was afraid of talking about it because no one liked him and I had responded with "No matter how much I don't like him, I care about you more than that." She left me on read. Now, I'm finding out from her sister that he's coming to the renaissance faire with us in a couple of weeks. She hadn't told anyone about it, but just expects us to be okay with it even though every single person who will be there that day knew how bad their relationship was. Im a little pissed, since I was supporting her through everything. Helped her move twice, stuck by when everyone hated him and she didn't even give me the decency to let me know he'll be there? I don't want to isolate her while were there, but I don't want to interact with him at all knowing what he did and has done. WIBTAH if I blatantly ignored him for the weekend? I'm trying to support and be there for /her/ but I dont know what to do at this point.
