It's not so much about deciding if I like him or not, it's more about interpreting different feelings and understanding the difference because I'm so used to building a wall and blocking/denying feelings. I've got myself in a bit of a rut where I've let it get so out of hand that I can't understand these feelings anymore.
A few months ago I went out to dinner with this friend and we spend hours talking and talking, I went home thinking he was absolutely amazing. But then I got myself into this idea that he doesn't like me, and that my 'feelings' were just because the idea was nice or I wanted him to like me or SOMETHING. Then I became adamant that though he is a very nice guy and very decent, I don't like him as more than a friend. Then as I said his sister during a conversation started talking about how he's been thinking about me in the past, thinking I was already aware of it. Now it's been on my mind for over a week, and I don't know if I just like the idea that someone likes me, or I'm flattered because so many girls are all over him and he chose me, or if I really like him and won't allow myself to admit that.

I know what I'm saying is confusing, I'm confusing myself just talking about it! haha

And no I couldn't tell him, I nearly did that with another guy and got totally rejected.
But this guy is a really great guy, he has good morals, a diploma, a job, we have a ridiculous amount in common (including very similar childhoods).
