DG...only concentrate on the things YOU can control. You can't control his thoughts or behaviors.
This is something I ask myself so that I don't worry about what my W is doing. Would you be ok with your H doing whatever (anything) but knowing in the end, you will be together with a MUCH stronger marriage? That is how I think of things right now. It really helps me to be able to only concentrate on me and fix my problems. Whatever my W is doing doesn't matter right now. I either fix me or be prepared to suffer more pain in the future.
