I was the WAS in my first marriage. I was 30 yrs old and we had been married 11 yrs with 4 kids. The unfortunate pattern I have seen is men don't take what their wives are saying very seriously until it's too late. I bet if you looked back there are times your wife was asking you to be more attentive and to step up and be a more equal partner.
It's great that you are trying now but I can tell you that she probably doesn't trust the changes will stick. The OM is doing the things you did when you were courting her. Giving her attention , telling her how special she is ect. This is where I see a lot of men drop the ball in marriages. They get too comfortable and take their wife for granted. I know women are guilty of the same and which causes some husbands to be the WAS.
It does sound like your w. Does still have some emotional attachment to you and that's a good thing. Usually when a women is done ....she's done.
Gal, have a PMA, thank her for the wake up call. Show her that you are sincere by continuing the changes. You have an advantage over the OM. You have a history, children and it sounds like she is still connected.
Do draw boundaries. It is not ok for her to be disrespectful to you and your marriage. There are a few threads on Boundaries on here. Maybe Cadet could post them for you. technology is not my forte lol.
