Claire, I have the same inclinations but have kept them in check -- mainly because I agree with Georgiabelle that he will think I'm guilt-tripping him and will blame me, but ALSO because I ask myself the following question: "Do I really want him to return just for my daughter's sake? And if he does return, do I really expect him to stay once she heads off for college, if he's not in the marriage for the right reasons."
Better to keep the information to yourself. I encourage my daughter to open up to her dad about her feelings if she wants to, but it's between the two of them to work that out.
