Second...Calls that revolve around anything other than your daughter....Those need to stop. As Sandy said....a begging, pleading, crying man is NOT attractive. Right now conversations about the relationship are useless until the OM is out of the picture. You also have zero control in how long he stays in the picture or when he leaves the picture. So stop hyperfocusing on him. We don't want to hear what a scumbag he is, because we know. What you have to know is that until he is out of the picture....you marriage is done. Second, is that there is no way you can push him out of the picture.
The real end goal of everything is to become the man only a fool would leave. By focusing on how messed up your wife is or how bad the OM is.....that doesn't help YOU.
You define what you can forgive and what you can't....That you control and no one else.
In the long run you might up only being her friend, but that is important to your daughter. You do need to get to a place where she can at least see you as a friend.....and right now you are not in a place to be a friend or spouse....Let's get you there.
