Or, in my case (where my WAH has "no hard feelings", and has actually been quite nice and accomodating to me), just convinces himself that people simply fall out of love, or just aren't right for each other, and that there is absolutely no possibility in the world that any of those feelings could ever possibly return, so there is simply no point in doing any sort of work at all to try to rebuild the relationship, despite the fact that a child is involved, there has been no infidelity or abuse, or that our families have invested literally tens of thousands of dollars into our marriage. Nope. Love just simply dies, and there is nothing to do except move on with no hard feelings. Sounds mature, right?
Sorry. I'm in a mood right now!
And... congrats GG! You definitely made the right call. He will probably be feeling bad, and have no one to blame but himself, since you are being nothing but nice! Have a great evening, whenever you get to start it.
