Sorry, couldn't resist. You don't need to wait for him. Start initiating. Whatever fills up his love tank. It may take some time to sink in, but when it does, there's a wonderful reciprocation.
Okay, so when is it time to talk? Well, still not yet.
DH and I, interestingly, had a conversation about this awhile back. About how R talks are practically the kiss of death in the early stages of rebuilding. Keep in mind, we've been reconciled for close to two years now, and we only occasionally broach this subject. (And usually don't discuss it for long.) Anyway, until there's a lot of good, safe feelings on both sides, it generally just serves to undermine.
I think it focuses on the negative. I really believe the key to rebuilding a relationship is creating new, positive memories and time together. You get enough of those in there, and eventually, the hurt becomes much more distant. This has worked very well for me.
You can talk about other stuff to create intimacy, especially if you are like me--I find deep conversations to be very connecting. Some of my favorite times with DH are just driving around in the car, talking philosophically.
