I am astonished that women are attracted to men like this! What on Earth goes through your head! Why did you choose this waster and idiot to be the father of your child?! Not only that, once you had finally clocked his true colours after failing to do so when you married him (I presume you did get married before you had children Utah!) you then had him back to do it all over again! Then you talk of more children with him! What planet are you on?
There are so many good and decent men and women out there who treat their husbands and wives in the manner husbands and wives should be treated (you can't count these idiots who just live together). Why don't you find yourself someone treats you well and makes you happy? You won't find them in pubs and bars by the way. Is that where you found this one? Is he what everyone says is 'a good laugh' and the 'life and soul of the party'?
Get rid of this prat Utah who will happily watch you and his own children suffer. Divorce is a big step but you can then find someone decent who you deserve. Otherwise you and your children will spend the rest of your lives struggling for money, always unhappy and never knowing what the next day will bring.
