Well, I'm kinda in the same boat. My Boyfriend of 3 1/2 years is pretty much against greek life all around (he thinks they're full of bitchy clones, and are only there to mold others into more bitchy clones
) and he doesn't like the idea of me rushing. I've talked to him about it, and even though he's against it, he's said that he's not going to love me any less if I do join one. Your boyfriend sounds like maybe he feels threatened by your involvement. It was ok when he wasn't in town, but now that he's coming back, maybe he thinks you won't have any time for him so he has to bash it. I would definitely have a talk with him to let him know that just because your involved doesn't mean that he's left behind. The fact that the name calling only began recently leads me to think that he might not be as anti-greek as he wants you to think. But hey, if after you talk to him you find out he really is, maybe you should think about how much you want to be with a guy who calls you a prostitute ( if not in exactly those terms) just for being involved with a group of girls...just a thought
