He seems more than capable of bringing up R talks on his own, and often. You might want to wait until he would like to chat more about it, but make sure it's on your schedule. A big part of this stuff is realigning that power/control balance in the relationship. If he wants you that badly you get to call the shots. You should be the one in control of piecing and reconciliation. And in that process, not before,, you become a team and end the power struggle.
No matter what don't let him crawl back too quickly. Make sure you make him work for it. He's gotta prove this is what he wants.
