Wow. A lot of men dream about this scenario and would like to get coaching from him how to do it. Not the men that come here, of course.
So. Let's think about him for a minute.
What incentive does he have to change his ways?
None.
Zero.
Zip.
Nada.
He has two wives. A legal one, and a common-law. Both take him back every time he calls.
I bet that hurts like hell.
It would for me. I recognize your pain.
But he has no incentive to change. None.
So who has to change?
The woman in your mirror.
Hugs.
