Divorce needed no money

I’ve been trying to get a divorce for a while now my ex put it all on me because he thinks I have better income (I’m a cashier in a grocery store and he’s on ssdi) I have a four month old (not my exes) and he wants to move on. It’s been a complicated trip full of one mishap after another. We are both done. Can any one suggest anything? I should also note that we live in separate states.
