Um, your relationship is "fine" and you're wondering if everyone can be, well, "fine" if you start dating your boyfriend's friend? Is this one of those slang things where "bad" means "good" and "fine" means "a huge disaster?" Sure, even in the best relationships we fantasize about other people. But if you're seriously contemplating dumping your beau for his bud, you're with the wrong guy—friend or no friend. The attraction to the friend might be just the wake-up call you need to get out of a relationship that isn't satisfying. But don't think it's all wine and roses with the friend. Remember, you have no idea what he's like in a relationship. And, by the way, I don't see the part where you say the friend has expressed interest in dating YOU. It's a Catch-22; if he has, he's not the most trustworthy of friends (or probably, lovers), and if he hasn't, well, your fantasy will remain just that. I say leave the boyfriend and go find someone who's more than "fine" before you hurt everyone here, including yourself.
