How often do greek life people have outsider BF's/GF's

[xstalkrx]

How often do people that are in Greek life have boyfriends or girlfriends that are outside of the college scene. Does it work out?

I am not in college. I have a stable career. I was dating a girl for a couple months and then she joined a sorority and began living on campus in the sorority house. At 6 months into the relationship things were still great but this is when she became comfortable in the sorority and really started going to all the parties and events and hanging out with her sisters a lot.

Needless to say, we were done before the 1 year anniversary. She had found a guy in one of the fraternities that her sorority associates with. She said she was in love at 6 months, but now, her "new life" as she puts it has drawn us apart. The formals she told me I "had" to go to are now reserved for her new fraternity boyfriend.

Were we doomed from the beginning? How often does this scenario actually work out where the couple stays together?
