Once again, just my opinion. If OM is EA, I don't think that will satisfy in the long run. So, if OM stays with his wife, your wife is naturally going to want physical affection at some point.
Start doing the little things now to make yourself that guy. You have been that guy and can be again. In my opinion, love can not be adversarial, and you've got to lead that for your family, which includes your wife.
Forgive her...love her...whether she reciprocates or not...
