Input: I’ve been friends with this person off and on for years. When we get a long it’s great. When we don’t it’s awful. Over time the bad started building up. 

He ditched me at party that he brought me to as a plus one to get laid (and will occasionally just get up and leave in the middle of hanging out bc he planned something else without mentioning). Then that same night asked me to come pick him up bc I guess things weren’t going well. Complained when I said I was drunk and couldn’t be of any help. 

He continues to be not emotionally supportive or understanding. When I was having a bad day &amp; we were supposed to hang out, he opted to cancel if I was gonna “be like that” as in not being in a good mood. 

Anytime I would tell him things I didn’t appreciate (for example flaking on plans with no texts or calls to cancel) he just threatens to bring up past things I have done wrong in the friendship. 

Did not even attempt to say bye to me when I was leaving across the world for 5 weeks.

I’ve had a hard time feeling justified in ending this friendship for many reasons, but I’ve opted to just not reach out anymore. 
Me and my roommates are having a party and one of them invited him (not knowing I’m not talking to him). I honestly doubt he would come, but I don’t want to feel backed into a corner if he does decide to come. 

So WIBTA if I uninvited him (I know he’s seen the invite on FB) or AITA for choosing not to be his friend? I feel like many of the reasons I have are small &amp; maybe I’m just being over dramatic?
