Boyfriend got kicked out, now I want to join!

[Moxie]

My boyfriend of over one year doesn't want me to join a sorority. I know this is a common issue, but my situation is complicated.

The thing is that he rushed last year, got a bid and pledged a fraternity. I can't deny the fact that I was opposed to the idea at the time, but it's because I felt he was doing it only because of pressure from his parents who were both very involved in their GLOs when they were in college. However, his dad's fraternity isn't even on our campus so it wasn't like he could pledge as a legacy. At the time, I had very little understanding of greek life...even less than I have now. He pledged, however, and I tried to be supportive even though he may have been able to see that I wasn't too happy with the idea. He didn't seem to fit in with many of the guys in his group, and I don't think they treated him as "brotherly" as they should have. Within two months of pledging, he did something "which looked bad for the fraternity" and got voted out of the house, apparently by a close vote. The incident was VERY minor and hardly a reason for him to be disaffiliated, but he was. He was upset at the time, but has grown to realize it was for the best and he's happy now. The incident, however, involved me in some aspect, so now I feel that maybe it was partially my fault even though he says he doesn't blame me.

Whew, that was long...I hope that made sense. Anyway, before I wasn't interested in joining a sorority because I wanted my freshman year to focus on academics and get situated with college life. Now, I'm interested in rushing and possibly pledging a sorority...would it be insensitive and hypocritical? How can I explain to him that our situations are different and will turn out differently, or at least for the best? I hope this isn't too silly a question, or too random/confusing, but I really am worried that he will take it as a personal offense if I end up joining.
