Quote: I have a gut feeling that she is still in contact with the OP. I have no proof.
I feel sure that you are right about this. For her to say that she's willing to work on the M -- and then not do it -- it's because she's still talking to the OM.
Quote: The worst part of the whole thing is trying to explain, without to much detail, what is going on to our 5 yr. daughter. She does not want mom and dad to live in two different houses.
It's hard, no question. My daughter, who's 4 and a half, was very confused and upset when mommy was gone. It helped her a lot when I simply told her "Mommy doesn't want to live with Daddy anymore." Now she understands what's happening (well most of it anyway, since I don't want her to know about OM) and she seems to be much more comfortable dealing with it.
The LORD is near to all who call on him, to all who call on him in truth." (Psalm 145:18)
