Oh my!!! My darling this advice comes from a child of parents with almost this exact issue. My father cheated on my mom and played the bounce-back-and-forth game for years, and it DESTROYED me. The divorce was traumatic, I won't deny that, but the not knowing was far more damaging to my self and my brother. I know how hard it is to let go of someone you love, I can't imagine how hard it would be to let go after so many years. But the CHILDREN deserve some kind of stability, and so do you. I know this will be hard for you to hear, but she isn't going to change. The best possible thing you can do is end this before it gets any worse. I also advise you to seek counseling for your children and yourself. Let your children express their anger, hurt, and frustration. But above all, do not add to their pain by talking badly of their mother to or in front of them. I wish you luck, love. Please feel free to contact me directly if you need to: email removed
