I honestly think this is the time for some tough love. There's no way, now, you can trust him or even begin to rebuild your M with him. If it were me, I would tell him something this in a friendly way:
"I love you but I can't continue to play these games. I'm tired, and I'm going to spend a couple of months away from our relationship. That will give you the space you need to figure out what you really want, because you clearly don't know right now."
Then don't talk to him (except about businees matters and the kids) for two months and see what happens. Otherwise, there's no end in sight to your saga.
The LORD is near to all who call on him, to all who call on him in truth." (Psalm 145:18)
