As much as i hate to admit it, what my friends think about a person I'm with or thinking about getting together makes a big difference. I'm talking about my really close friends who i've known for a long time. It's not a matter of worrying that my friends will think less of me. It's that they usually end up knowing who's gonna be good for me, and who isn't. I've dated people who my friends haven't really approved of, and although they've been as supportive as possible, they always end up being right. It's not even the power of suggestion that gets me in the end, it's all the things that i've been concerned about in the beginning, but chose to ignore because i really wanted to try something out/making something work. The way that i would approach it (although i'm single so maybe that's indicative of who's adive you SHOULDN'T take) is if i wanted to casually date the person, i would, but i wouldn't get too involved, and i'd sorta test the waters. If she turns out to be great, then take it a litte further. But as far as my experience goes, my friends are the ones who are able to think with their brains on this issue, while all my blood is rushing elsewhere, thus rendering me a walking hormone and getting myself into trouble that is a pain in the ass to get out of later.
