Should I ask him? or just forget about it? :)?

I met this guy when we were in freshmen year in college. We became friends, and eventually, closer. We didn't really admit what we felt, but we talked everyday, called each other, spent time daily, watched movies just the two of us. I was the closest girl in his life, and he was the closest guy in mine. Most of the time we just tease each other but there are moments when the time seemed perfect, that we'd dropped hints every now and then, but then we found out we are actually blood related! it turns out that his mother's my second cousin. it got awkward after that, but eventually we became even closer, and i well, fell for him even more. then, we had a huge fight, and we didn't speak to each other for months. Now, things are okay again, but we're not as close. Until now, I can't move on. I mean, what if we really had something, but because of our inconvenient relationship, he didn't make the move? or is that just wishful thinking. I'm afraid that if i ask him what we really had that it would create yet another rift between us. yet if i don't, i don't know if i can move on.. what do you think? :) let me know. thank you! :)
