She should go ahead and divorce him and ensure the money that belongs to her from the marriage goes to her children and not him. Staying in a marriage where he is hoping you die soon so he can play the field isn't exactly "marriage".

Put it in a trust fund.

The woman I was helping has a beautiful and healthy 4 month old baby girl. I'm past trying to psychoanalyze her, but I think she has these kids because men have treated her like crap all her life and she probably feels that she can get the love and trust she wants from the children.

I doubt she will ever mature past that point. I guess the hurt runs too deep after the physical and mental abuse and betrayal of her first "love" she underwent as a teen. (Betrayal being the beatings he subjected her to).
