Yes I think most get a real rise out of the cheating. If it creates a feeling in her and also a feeling in the husband that slowly pushes them away from each other yes it will destroy the marriage but that possibility is always there if you don’t take care of your marriage. Thats why I say if you have a feeling she is cheating don’t pull away but start paying more attention to her. She will start wondering why. If you have a strong feeling she is seeing a lover grab her when she gets home and go down on her. Have really hot sex with her and it will flip her out. Nothing makes your wife more interested in you than surprising her and doing things she doesn’t expect. Routine bores women and variety and spontaneous behavior excites them. You can slowly show her you know about her escapades without saying it and that you love it. You both can have lots of fun with it and make your marriage exciting. Even if she is fucking another guy she won’t leave you if you have some excitement in your relationship.
