Is OTHER wrong in the post ? POST : I am currently second year in university, recently at the beginning of this year I made a new friend, let's call him Jin,  and grew fairly close to him throughout the year. I am using my house as a venue for Jin's farewell party as he is leaving the country and has no where else to host a party. 

My ex had a history of being controlling due to past issues and I have put them aside to love her as she is. However I have gotten fed up with not being allowed to socialize with people she dislikes. She especially dislikes Jin due to her being in the same highschool as him in the past. I have spoke to her repeatedly and in my eyes I can see that he has changed from the way she described him, however she refuses to believe this and still holds her opinion of him. 

This past year as well I have not gone out to parties or basically meet anyone other than my ex as she gets insecure very easily. I have lost many friends due to this. You can find out more on a previous post I made on r/relationships. 

I think I have reached my breaking point, but I still have doubts on the breakup. AITA for breaking up with her due to not accepting her insecurities and hosting a party even though she was against it? Was I also wrong for being friends with someone she didn't like and not respecting her opinions?
