Is OTHER wrong in the post ? POST : My[21] best friend[21] was in a relationship for 2½ years. I hate that girl. All our friends thought she was not the right person for him, and that she sees a father instead of a boyfriend in him. He always put with anything she doled out to him saying he loves her. Him saying this, meant that I could not say anything to him outright

Things reached a new low yesterday, and he decided to break up with her. I nudged along some things, and brought some thoughts forward which he already had. You can say I'm indirectly responsible for him reaching that decision, although, he was going to take that decision some day. The only thing stopping him was it was his first love, so he was a stupid idiot in love. 

Thing is, I should feel guilty, shouldn't I? Instead, I can't stop a grin coming to my face. She's toxic as fuck; she screamed at him to stay away from her, blocked him on a whim, and she's being repeating the same arguments every time they fight, which is pretty frequent. He's family, he's like a brother to me. 

AITA for feeling happy that he's breaking up? Should I feel guilty about it?
