LW I know you have really tried to understand why or how WW can be so far apart from your S and does she not as a mother want to be more involved. At some level this facilitating of contact between them could be your attempt of ensuring they have a good relation no matter what the outcome of the MR. While I agree it is honorable, I think your S is old enough to decide when to forgive his mother and bond with her again. If WW is not ready to give the depth of love your S should be given, it might cause more harm. So let them figure out the time and path for their own reconciliation. As always your S knows you are his rock.
