Is OTHER wrong in the post ? POST : Hello Reddit, just thought I'd run this by you all.

&amp;#x200B;

So there's a concert to one of my favorite bands, (not all-time but still incredible group) and they're coming to my city in 4 months. 

&amp;#x200B;

My boyfriend wants to go, and he talked to a friend of his/ours (40's) (my boyfriend is 19, I'm 20) and they agreed to go together, without my knowledge. 

&amp;#x200B;

My boyfriend promised me the tickets first, but maybe forgot, who knows, he wouldn't try to hurt me on purpose so he is obviously NTA. So he tried to offer that we both go. Friend says "I don't want to go with her" alongside saying he will feel like a 3rd wheel (age difference???? hello?) and that I will cause a fight with my bf because I don't feel like I'm getting enough attention. I know that I'm there to listen to music and probably get drunk before. Not to be an attention whore. I never am, and NEVER will be.

Some background info: I was in the hospital for a suicide attempt, and my bf decided to spend his time with aforementioned friend without me knowing, because he knew it would make me upset. But he did it for his own good reasons, again, not the asshole. But the friend (40's) of his did it knowingly that it would hurt me, and doesn't care. He tells my boyfriend to break up with me constantly, and he used to do the same to him (tell me to break up with him). The guy is a total prick, has brain issues and memory issues. Can't hold a job because he will snap because of some anger issue/mental disorder that  he has admitted to killing people before because of. 

&amp;#x200B;

I don't want my BF to go alone, because this friend will spend a lot of the time bitching about me.

&amp;#x200B;

So am I the asshole? Typing this fast because this JUST happened less than 5 minutes ago, but I will clear up any confusion with an edit or answering questions in the comments.
