Make sure you tread carefully. I agree that it is time for H to make a commitment in one direction or the other instead of flip flopping, but you need to be prepared for what the answer is going to be. Bringing up MC, is probably the best bet. You are awesome about talking to H and saying things well. Saying something like I would like to start MC with you to help continue in a positive direction will be good, but an ultimatum may not be. Have something ready in case he doesn't want to start MC. Make sure you ask him what he would like to do, but nonconfrontational. If he says yes, then great. If he says no, then be prepared to hear him out, to express you feelings, and to possibly move on without him. H seems to need a little bit of time to think things over so just make sure you don't do an ultimatum, but instead let him think about it and if he says no and means it, be prepared for what you want to do instead.
Of course this won't happen until after the new year, so for right now just enjoy the holidays!
