However, right now I am preparing to confront the W and her affair. This cannot go on any longer.
Again, it comes back to you having a PLAN.
What are you going to do in this confrontation? You going to say "him or me"? "I wont live in a 3 person marriage"? Then be prepared for her to say she doesnt love you and doesnt want to be with you and is ready for divorce.
What then?
Im not saying that confronting is the wrong move. I just think you need to be prepared that it wont go as you hope or expect.And if it doesnt, whats next?
