Craig, I cannot believe how similar our situations are, although my h had/is having an affair. But we have not had a cross word (ok, we did twice) in 15 months. We are cordial and kind to each other like good neighbors.
I do not push, I just live my life. I ofter wonder if something will change. I think he is waiting for our son to graduate high school in June - though I am not sure. I have to wonder what is going to make my h change his mind.
This civility can get to you though, cant it? Sometimes I just want to shake him and ask him what is he thinking?
But I know that God has a plan and I trust in Him.
