Divorce is always difficult to deal with. Going thru it during the holidays seems to make it worse. Its been 7 years sinse my husband at the time, walked in from work on December 14th, and informed me he was moving out. He said it was because I had changed too much sinse AC died. Reality was, as I found out a few days later, he had someone else.
It was devastating. Everyone is right, concentrate on making/keeping your kids happy. I had no children, but I had my neices and nephews, and they got me thru it. I also decided to move out of state. My nephew helped me, with the understanding, I would get him back to his home as soon as I was settled. He decided to stay.
You will be alright, and so will your kids, it will take time.
Love and Hugs
