Space, time, no pressure all is good. If she is having a affair it is bad - she keeps feeding her in-love feelings, you lose self-esteem and your family loses.
Boundaries about your wife spending time, money, love, affection, energy, and family resources on another man. Boundaries are about her behavior. A boundary is not a ultimatum, it's not pressure and not a push. It's a choice on how you let someone else treat you.
That is something that I am working on. I am doing more by myself, she will be forced to be at home or at least be with the kids. She knows I don't approve, she says there is nothing, but I have my doubts.
