Quote: He said he wants his family and that he is just so tired all the time
YEAH! I think some clarity may be starting to set in. I think you did the right thing. An affair is a fantasy. By you laying it on the line for him ONCE he is starting to have some clarity will help him to look at things realistically. If you had done that before the clarity began, it would not have mattered.
GOOD FOR YOU! I hope he sees his selfish ways and what a loving stable family he would be throwing away for the twisted OW. If he left you for the OW, you would probably still love him even though you got a divorce. If/ hopefully when he leaves to OW for his family the OW is going to hate him. She will put him on a guilt trip...it will get ugly. THAT'S NOT LOVE.
