What is the penalty for a husband that abandoned his wife?

I don't think there is any penalty. Get a divorce. I guess he was taking the cheapest and easiest way out of your relationship.

It depends on the state and what you mean by abandoned. More details are required to answer this properly.

Abandonment of a spouse and children is not a prosecutable crime in most areas. What it is is grounds for divorce. However, it will not be looked at kindly by the courts when deciding support, distribution of assets, visitation etc.
