How do I help my daughter repair her relationship with her dad?

Mother Talking With Unhappy Teenage Daughter On Sofa

DEAR DEIDRE: WHEN my young daughter saw photos of her dad – my ex –  with a new woman, she felt betrayed and hurt.

His response was to cancel her visit for Christmas, which hurt her even more. I really want to help repair their relationship, but he won’t communicate with me.

I’m 46 and my ex husband is 48. Our daughter is 13.

We went through a horrible divorce just over a year ago, which our daughter found very distressing.
