My friend was with this girl for about eight months. He is 22.

While he was with her, he would go on and on about how she was "the one" and how they were going to get married, etc. 

She recently broke up with him because he was moving way too fast in the relationship and he needs time to work on himself and deal with his anxiety.

He completely lost it after this. We ended up having to call 911 and have him taken to the hospital because he was calling her and us threatening harm on himself. 

He constantly calls her asking why she can't take him back, and he told us that if she's in the city, he might go to her place and "ask her in person". 

Well, me and my friends all took turns spending time with him after the hospital visit and on my turn I just lost it after hearing for the fifth time how he was going to "get her back."

I told him he was being creepy and pathetic and that she has made it abundantly clear that she doesn't want to get back together with him and he needs to stop all this behavior. 

He got really pissed and kicked me out of his apartment.

My friends told me that I probably could have done it in a nicer way but that they agree with me.

So AITA for telling him all that?
