In short..my advice is to go ahead and spill your guts. If this is as important to you as I interpreted it, then don't keep it in.

BUT CONSIDER THE OUTCOME:

Based on what you've said alone, the general vibe I get from this dude is as most here have said. The dude's not worth it. Looks like "he's just not into you" Jane. Not the way you, anyone, deserves.

I could be wrong. After you come clean he may take you in his arms and say he thinks you're his soulmate too..but I give you low odds on that happening.

Consequences: The friendship will likely be forever altered.

Choice: Is it so important, so deep a feeling that it's worth the risk?

Maybe I've achieved or have fooled myself into thinking I've achieved such a robotic level that I can command how my feelings are invested like I would a financial portfolio, but my advice is to try to direct these energies toward what is convenient for you.

Here's what I do:

I like this girl. Probably as much as you like this guy. I'd use the term "soulmate" if I wasn't careful about what I write. I don't think there is such a thing, though. I think we only really, REALLY like our respective love interests and we're keeping the feeling alive because we all want some love/drama in our lives. Making myself concious of this I continue to be master of my own life and if I desire to, I can hang on to the fantasy/hope that one day we'll be together, while still leading an otherwise unaffected life. I go out, meet new people, open myself up for other opportunities. Only "hope" remains, but I'm not proactive about this. It is what it is, but it lives on it's own, without assistance from me. I'm busy living my own life.

And so should you.
