There is no right or wrong answer here, especially given the personal nature of the decision. The question that seems most relevant to me is what affect will ML with him have on YOU?
I a coming at this with a man's eyes, and I do not profess to understand women completely (if I did I would not be here).
And, what control do you have over his decision to leave/not to leave? None. Don't fear what you cannot control, just prepare for the worst. Make peace with the worst thing that could happen and you will find some very interesting perspective on this whole sitch. One of the posts I read suggested mentally going to the "wrost place" in your sitch and realizing that you will still be ok. Can you do that?
If you can do that (and I know you can), then what do you have to be afraid of? You know the answer...
