Can I be charged with abandonment after leaving my husband and my kids don't want to have anything to do with me?

It is highly unlikely that you would be charged with any crime. However, the fact that you abandoned your family could be used against you in future custody and support proceedings.

People are usually not charged with abandonment in a divorce proceeding. The fact that you left is an issue in a custody hearing (i.e. you didn't want your kids). You need to consult with an attorney right away to find out what your rights are.
