well he doesnt have to have a job he still owes you child support and if worst comes to worst you can get his taxes or put him in jail [not sure what the rules are in your state but its the state you live in not his]
Is there a reason you don't think he's moving back?
You can be a single mom, sometimes it's easier. Without a jerk {sorry I *hate* men} I am doing it, but it's hard, but sometimes it's better then the guy. Justin, my babies daddy, when we where together he was a jerk to me, comparred me to other girls he dated before me and acted like I was his slave, he'd yell at me, then make me feel guilty when I wanted to go back home.
This time, I am doing better cause I know nothing will change and I have to deal.
I wish I could help, but I know nothing about your situation and I am a natural mess up... but dont worry, make him help you, you have that right.
If you need info on rights I am sure you can find them. or I can help you find them. I live in New Jersey, but I am sure I can find or help you someway
