PLEASE HELP MY PARANOIA!

[cnut]

Okay, some of you may laugh at this post but I hope some of you can relate to it and help me out.
My girlfriend(damn good lookin!) and I have been dating for about four years now since high school and we both love and trust each other(mushy right?). We are both transfering to seperate universities that are less than an hours drive apart. Ok now u have the background to my problem but here is were my paranoia starts:
My girlfriend wants to join a sorority in order to meet people but as a boyfriend it is natural for me to be objective to this. I have heard many stories from friends in greek and non-greek individuals about the inituations and socials and stuff. Stories like female pledges having to strip down half naked on tables for different fraternities, not enough time for the boyfriend because of act.... I've just heard of many relationships not working because of one guy/girl in a frat/sor.
Can someone relay some logic onto this for me? Do you know anyone in the same situation? Tell me whatever will be truthful and helpful.
thanks
