Good friend of mine met amazing girl from our college. Before they got together, us three were best friends. So, there was best friend of his girl (which is my best friend) who likes to party a lot. His gf is in apartment with her best friend and three other guys which they met yesterday.

I don't know if he knows this. They had very hard time when they aren't in LTR. So after all bullshit they've been through, they are finaly together and they both look so happy.

I don't know what to do. Should i tell my friend about that? Or maybe not?

PS. He has depression, and telling him about this will only make things hard for him.
