I have heard many story how some husband treated the wife so cruelly and leaving the family alone. What I feel is, we as the wife have to assess whether the husband is worth us salvaging the marriage. It can't happen one time and most likely to repeat again. So how many heartbreak we have to go through before he will come back to the family.
What I have learn is that, rather to start in a marriage and be miserable, then get a divorce where both party will be happy. In fact, the children life will be most stable and enjoyable instead of seening the parent quarrelling and unhappy.
