Try getting a house alarm system. Set it every time she goes out. If she is a stay at home mom then start cutting off some of the things she takes for granted. No more cell phone. If she wants to continue the A it will be on her dime to pay for the means to do it. Same with other things. No family money will be spent facilitating the A. Move your paycheck to a separate account so you have control of the family money. Cancel combined credit card accounts. Let her get her own and pay for it. Again, family money will not be used in any manner to facilitate the A.
When exposing the A to other people first think about how things will be like if you and WW work things out. If it would be weird or cause problems then don't expose it to people you will have to be around in the future. OM's W is a different story.
