I do agree you're kind of in a tough spot. It sounds like you guys are doing this relationship long distance at the moment (or at least that's the vibe I get from the end of post #13). My advice would be saying something to the extent of "I feel awkward being this far away from you and seeing these girls go after you without much regard to the fact that we're dating." The guy doesn't mean ill, and it sucks having to be away from the girl you're in love with. Odds are he does get a little ego boost out of it, and that's probably the extent of why he gets into this. I would say that you trying to cut off his text-conversations in total with these girls wouldn't go over great, but if you can pick out exactly what in them bothers you, and bring that up to him, that might be more effective.
