Thank you both for taking the time to respond. I don't really know what an 'I-Thou' relationship is. Forgive me if it's something obvious that I should understand.

I would never come on strong. I don't have a clue how to 'come on', period. Normally, that wouldn't matter, it's always been something the other party takes care of. We have a number of shared interests (we met as a result of them) so that won't be a problem. The only problem I can see is getting so wrapped up in our mutual interests that I'll never know if he wants anything more. How do you say goodnight to a schizoid that you're sharing a room with? How do you know if he wants you to stay?
