Confused. Very confused.

[Kiddo]

Last night my best friend came in to my room and told me he loves me.
I love him too. And I'm not always sure in what way.

The thing is, I'm sort of on the brink of something with another guy (incidentally a good friend of both of us) and I'm really quite excited about it. My best friend knows about it (naturally), he said that he's insanely jealous but he really wants to keep things the same between us if I did end up with the other guy.
I really don't want him the just "Nice Guy" me and be "Cool With It" if it's really hurting him, but equally I don't want things to change between us because I love him to bits, he's my best friend in the whole world.

Sometimes I think that we should try it, we're very intimate anyway and it wouldn't actually be that much of a leap, but I'm enough of a realist to know that it would have to end someday. A friendship is more stable than a romance, it's less likely to go sour (especially for me, I have a talent for ruining relationships; pushing people away, losing interest etc.)
I also really want to give this thing with guy No.2 a go as I have a feeling that (a) it's already gone too far to U-turn now and (b) I might not get another chance with him, feels like I should grab it and give it a go.

I really don't know what to do, my friend is usually the one I go to with relationship problems, it's kind of ironic really...

Corny enough, follow your heart. Go with the one you're simply most interested in, that's the only fair decision to anyone involved.

If you want to try to take things to a new level with guy No. 2, then do so. If your best friend really loves and cares about you, he'd wait until you were ready to see if a relationship could work. But, keep in mind. I've been dating my best friend for 2.5 years. We were best friends before we dated, and still continue to have our relationship grow everyday. Sometimes, the best relationships come from friendships.

Follow your heart. Pick the guy you like the most, that you can see yourself with the most and go with it. I'm sure if you explain it to the guy you don't pick, they'll understand if they're both good friends of yours.
