I agree with what's been said ingalot. If you're not 110% comfortable, I'd hold off. A "build up" approach could work, but it puts...how to say this...it sort of sets the expectation of an end goal in his mind, if you take my meaning, and I'm sure you're cognizant of that as well. Thus, I'm worried you'd be prone to hurry yourself along, so to speak, and end up with regrets, which we don't want for you. Do you follow my (admittedly pessimistic, but bear with me ) line of thinking?

There's no rush, none at all. Don't commit to anything until you're 110% ready, and not a moment sooner. If he cares for you, truly cares, he'll understand. If he's behaving in the manner you say he is and genuinely means it, there should be no problem.

Hugs, and I hope things go well,
