hi--
so this relates not at all to greek life (other than the fact that both bryan and i are greek), but i've always gotten advice for different issues from this site, so i thought, hey! why not?
so, anyway, there is this boy, bryan, whom i met 2.5 years ago when i was a perspective student at my current school. we chatted a few times over email while i was trying to decide where to go to school, and i think part of the reason i am where i am here is him. he has always been someone who is there for me no matter what whenever i need him...someone who by just seeing him, brightens my day. he's had a girlfriend most of the time i've known him (i always thought she hated me...he told me she always thought we had a flirty relationship), but he doesn't now. they broke up for a few weeks about a year ago, and they have been apart for at least a few months now. i had brunch with him and a few others yesterday (which was fabulous since i hadn't seen him for a bit...he had called me a few weeks ago to get together, but i was out of town), and it just reminded me of how much i like him...maybe even love him. i feel like he might be in a situation right now where he's been attached for most of his college career (he's a senior now) and just wants to have fun, and i really don't want to ruin what is one of the most important friendships of my life...but at the same time, i really do love him. please advise!
