I'll add that he's not here asking for advice on how he can change so he's not going to change by you coming here asking for advice about him. You are the one that has to change if you want him to change and that means you have to stop the enabling, the relenting to his requests and the inaction in getting legal mandates in place when it comes to visitation schedules and child support payments.

You change and and get the strength and confidence to do what you need to do and he will be forced to change his d-baggery.
