WW having affair and pushing for divorce

[mtb1981]

I get that you're mad about it, but what can you do about it?... Nothing. You can't control what she does, so you have to accept it and train yourself to not be bothered by it. It's not an easy task, but with time you can get there. I don't know what else to tell you. You asked for advice on how to deal with the situation and talk to your S about it, but you're only focused on and still way too hung up on stuff you have no control over. What can can do is decide how to react to it and decide what you're going to tell S if he asks. Stop wasting your time being mad about it...
