I don't mean to come off as insensitive but I think this is a prime example for why people advise others to cut off their ex's completely and for good when the relationships are over.
He is taking too much of your space. In the future, to avoid this kind of drama cut things completely off at the break up so you don't have to worry about this kind of thing.
As for this situation. You need to cut the guy off. Not for anything other than you don't need this ish in your life.
He's runnng around thinkin he's the **** and you and HER continue to stick around. Her for being in the room that night and YOU if you keep talking to this fool.
