I doubt very much that u would be allowed sole custody of the
children - unless u can offer irrefutable evidence in court
to prove that he has been an unfit FATHER to your chidren. Its an
uphill climb so its better tthat u relent and accept it as the
court deems so.
As for his infidelity - i do emphatize with u but its better to
let go and
reconcile to what is available to you now and see what can be
worked out amicably lar.
I agreed with you that it is very hard for her to gain full
custody of her children, all the more if she is not working
now.
But I do not think she is a woman who will not try to settle
things as amicably as possible with her husband for the sake of her
children. That is probably one of the reasons why she forgave her
husband back then - for the sake of her precious children.
The problem now lies with her husband. It seems that he is doing
his "best" to ensure that he will provide as little as possible for
painfulcat and her children. In this situation, I believe that it
will be better for painfulcat to fight it out and gain every single
cent possible off that unfaithful *******, for the sake of her
children if not for the sake of herself.
