Be the person he wants to be with... don't pursue, beg, cry, etc. You wanted to work on your M, you can still do that. You can reconnect with him even if he's unsure but you have to tread carefully. If you come on too strong, he may end up walking in the other direction. Don't force any R talks on him. If he wants to talk, let him.
You have 7 years together, and a daughter ... you just don't throw that away overnight. But you will need patience and steadfast, but not overbearing determination.
Karen is also right about posting here. Not sure what to do? Need to vent? You'll get lots of advice...
