If you get divorced, it is important to divide debt in the same way that you divide assets. You need to split things up with your ex so that the lenders eventually get what they are owed.
Do you and your ex still run into sources of conflict, despite your divorce? Many couples do. If you have kids, it is important to remember that children learn from this behavior. They're like sponges, and they see everything that you do and say, whether you're trying to teach them at the moment or not.
