Most Helpful Guy
Generic awnser I'm sure but, you should start dating other people, like really giving them a chance, cuz sounds like you might want more then friendship here. He might see that two. Don't want to lead you on or has somthing going on himself and talking to his ex isn't very kind to his current situation. Or he don't want to get caught up emotionally being so far away. Eather way he's doing the healthy thing right now. If you really want to be freinds respect his space, let it go and maybe you two will have the friendship later on.
