Is OTHER wrong in the post ? POST : So there is this couple (28 M &amp; F) that I (21F) have known for several years. We are all part of a large mutual friend group. They are getting married this summer and I am reluctant to go because I am still hurt over a situation that happened 2 years ago. 

The story goes my bf (24) and I were hanging out with the couple in their home having some beers and chatting. She was sitting on the couch next to my boyfriend and I was sitting on the floor while her now fiancé was sitting in a chair. He told me that I could share the chair with him so I didn’t have to sit on the floor. Thinking nothing of it, I sat next to him on the chair and we continued our conversation. She went ballistic on me. Started calling me a whore, a bitch, a skank, all because I sat next to her boyfriend on the chair (even though she was sitting next to my boyfriend on the couch) and was accusing me of trying to steal him. I ran home sobbing, guilty over something I didn’t do wrong. My boyfriend was comforting me and her boyfriend eventually came over to apologize for her behavior, blaming it on the alcohol. 

After this situation happened, I was willing to let it go if she had just apologized for the situation. Rather than apologizing, they stopped talking to me for 6 months. My boyfriend tried asking the couple what their problem and her boyfriend stated that her feelings were “valid” and they needed space from me. I don’t know how someone could need space from me while all I did was sit next to him in a chair? Even my boyfriend believes that they’re the fucked ones in the situation. 

By the 6th month my boyfriend was trying to get me to speak to the couple and let bygones be bygones. I didn’t want there to be any more drama within our friend group so I just let it go. I secretly haven’t let it go because I was extremely hurt by her comments and her boyfriend defending her even though he was the one that asked me to sit next to him. They are getting married out of state where I will have to be spending over $200 for a plane ticket and spend even more money on a hotel. My boyfriend is in the wedding party so I feel like I have to go even though I don’t want to. 

I’ve expressed my feelings of still being hurt to my boyfriend and other mutual friends, but they all say I should let it go because they have and it happened over 2 years ago. AITA or petty for not wanting to go to their wedding? 

TLDR: couple is getting married and I don’t want to go to their wedding because the woman called me harsh names over something I never did and she never apologized for it.
