I am hoping you guys will be able to rekindle a friendship for the sake of your children.
It seems like she is hurting. She was replaced. And her pain is causing her to lash out. Makes no sense because she is the one that left you and was unfaithful. Sounds like she needs to villify you in her mind instead of facing up to her own mistakes. . She really has some growing to do.
Regardless, you can only focus on you and your own growth. And keep doing what you know is right. It sounds like you are a great dad and really have the kids best interests at heart. Hope you have a wonderful hoiliday!
