I love my room mate

I think I'm in love with my room mate. We've been best friends for 4 years now, and as of 2 month ago, we became room mates.

We always connected and got along extremely well. About 2 months ago, she asked if I was a good kisser. One thing led to another and we "made-out" for about an hour.

The next day, she told me I was the best kisser she'd ever kissed. We can easily talk about it with no awkwardness at all.

I know that being in such close proximity with a member of the opposite sex can lead to forced attraction, but I've had these feelings for much longer than we've been living together.

We've both made the comments that "We're best friends" and "This would never work because we're too close" and things of the likes, but I'm always lying when I agree.

I don't know what to do. I know in my heart that I love her more than life itself. I think that's the main reason I won't confront her about how I feel. The thought of living forever knowing I'm missing out on the love of a lifetime isn't near as difficult as thinking of being told "It can't happen" and losing her.

So my question is, where exactly do I go from here? It's sad, I'm a mid-twenties male, and I don't even think about the sex or anything of the likes. I just want the laying in bed watching her sleep, or feeling her next to me during a movie, or just knowing that when I get home, she'll be there waiting for me with details on what she did that day. Is it normal to think this way?

The more I think about it, the more I realize that though nothing else in the world matters more to me, I cannot be with her, because I risk losing the most important person in my life.
