I understand a lot of what you are going through. I went out of my mind when my xh introduced his ow to my kids. They would go out and have fun together and she would do their hair. I hated her touching my kids hair. Now three years later (yes he is still with her) but my girls complain about their dad not spending enough time with them they don't even mention ow. She does not even rate in their minds. It is not that they do not like her but they need one on one time with their dad. He does not get it.

You are right you cannot do much about om. Just be there for your kids. I know it is hard but do what is best for your children. Don't make this about revenge on your w. Live your life with honour and dignity. You need to be the sane one and be the foundation for your children.
