Ever heard the expression, "cut your nose off to spite your face"? These negative comments you've been making is hurting you more than her. If you want to save your M then you will have to be more attractive than the OM. What is she getting from him that she wasn't getting from you?
You may have to set up arrangements where someone can be the go-between when it's time to exchange the kids. At least, until you can control your emotions better.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
