Your attorney is right, leaving the state is a bad idea. Leaving the county might even be a bad idea.

Your attorney is possibly wrong about him not being responsible for debt in your name. Unless that debt is your from before you married, he will be responsible for half.

Your attorney mentioned child support but I'm surprised that he did not mention the prospect of spousal support. Housewives are usually able to get a healthy allowance at least for a limited time.
