My H was mad at the kids in the beginning of his affair. As an amateuer C I think it was because back then, not planning on leaving us yet, the kids seemed to be what stood in the way of his happiness. If we didnt have them, he would just leave.
Last year, and last night even, laying on the couch with my kids, both in my arms, I was feeling I am fine, we are fine, we will be fine anyway. And I am glad you feel and know the same for you guys as well... K
