I don't think so. I'm thinking about the WAW who posted this morning that if her Husband made any kind of threat like this she would react badly to prove her point. Also thinking about the Wives that said they finally realized their Husbands loved them and were the ones for them because these good and wonderful men treated them gently, respectfully and gave them their space and free will. I can't control what she does and I believe that by making it known: 1. I've never cheated on her in 17 years which I have told her, and 2. I don't approve and neither does our marriage counselor not like a non approving nagging mother, but because sex with others really do prevent anyone from doing the hard work they must do as both my wife and I have said to each other before we can be in a relationship with anyone!
Final thought. My wife has always told me that when as a child her mother lashed out at her it was NOT effective, but what really caused her to think was when her mother would tell her I know you're better than this and I recognize you will do what you want (she was 18) but I'm disappointed.
OK Steve I know you don't agree, but this is my course. I followed it last night and this morning she was VERY kind to me - told me I looked good and came back in the house before going to work to bring my sunglasses from the car - something she normally would NOT do.
It's a narrow line, but I believe this is the right course for me right now. Believe me - if she were to move in with another man or start openly telling me she's having an affair than I would up the stakes, but like Poker you don't go ALL IN, unless you're really prepared to lose everything, and it is not right to give an ultimatum now.
