It sounds like you're taking cues from him, which is a good thing, if you feel he's timid. You've expressed interest but haven't left his feelings out of the decision, either. What guy doesn't like that?
Yep-pain is all part of the process. There's no getting through dating or even marriage without it. I do still feel concerned about his spiritual beliefs, though, because that is crucial. I'm concerned that you'll develop an attachment to him, only to find out he isn't devoted to the Lord with his whole lifestyle. I even know of people who were in seminary that I'm certain didn't know the Lord, so this one takes a lot of time to really determine. Maybe if you watch for cues, see whether he invites you to church, see what kind (if any) church he goes to, whether he's involved, and that sort of thing. That is truly a better way to determine whether this really is God's will.
We're rooting for you.
