My H (who moved out in Oct) came to dinner Sunday night. It was the best "family" dinner we had had in a very, very long time. I suggested to him that we do this periodically and he tentatively agreed "for the kids". It makes me sad that my youngest will have zero memories of being with two loving parents, and I think this is a good step for him. Will probably be good for your little D too. And, if those dinners give H and I a relaxing time to get to know each other again, maybe something more will come of it. And maybe not. But as long as I can take it, I would like to have that time as a family for my children and for me.
The big question is whether you can take it - the raised hopes that may be dashed?
