I guess I'm not seeing where in the post he is putting this girl on the back burner... by participating in greek week?

I think that it is totally reasonable to periodically have a hobby that takes up more time than your relationship. Ebbing and flowing is natural. I think too many undergrads have the idea that being in a relationship means you spend 100% of your free time with that person. [To the OP:] It will be better for you as an individual and your relationship if you think of something else that gives you satisfaction and focus on that while your bf is busy. If it is meant to be, you'll be there for each other when each of your schedules settle down and will appreciate your time together that much more.

As far as not liking the attitude of his friends, keep an open mind for a certain period of time. A lot of times a bunch of decent (but younger) guys get together and think that the way to be cool with each other is to act like chauvanists. Most of them grow out of it but some of them [the ones that come on message boards to brag about their frattiness] don't.

I agree with 33girl and think you should ask yourself if you aren't willing the inappropriate behavior out of them because you expect it from guys who wear letters. There are many non-conformist fraternity guys out there, probably including your boyfriend. I think you should make a concerted effort to get to know them unless or until they give you specific and unambiguous indications that they disrespect you. At that point, you can either try to salvage a relationship and put up with their shenanigans or move on to somewhere (and someone) else where you'll fit in better.
