She probably makes him feel good. She makes him happy. She accepts him for who he is and makes him feel special. The other things are superficial.

It would be better for your children if neither you, nor your husband lived with OP or remarried. Divorce makes them unsettled and insecure enough, remarriage would only add to that. That's just my own two cents. There are some instances where remarriages do work well, but statistics are against it. A large majority have many problems, and I personally wouldn't take that kind of risk with my kids. I'd have to know and date someone an awfully long time before I went there... of course by then my kids would be out of the house so that would be fine.

There is no arriving, ever. It is all a continual becoming.
