Ex regularly drove without license and over the limit/on drugs
It wasn’t lack of knowledge, or lack of money, or needing to be ‘help’ to family 
It was because he was a selfish bastard who thought the law or indeed any rule or social convention just didn’t apply to him
All PPs have dealt with the driving stuff so I’m gonna add this:
Selfish bastards who think they are above the law, and who try to involve others in making excuses/covering up for their crimes are not likely to be loving caring and kind to anyone except themselves
OP you are pregnant, and that can be a point at which abuse starts or increases, ditto times when the potential abuser feels ‘caught out’ or ‘unfairly’ criticised
You are on here teaming yourself to him & his bad choices with ‘we’ and asking for help to solve the natural consequences of his bad choices
Maybe you are a bit dodgy yourself and fully support his bad choices 🤷🏻♀️
But on the chance that you disagree with what he has done and are at heart a decent person then I’m gonna urge you to have a chat with someone in rl who can support you
Because his level of entitlement wrt what he has done may well be indicative that he is selfish, entitled, blame-shifting & consequence-dodging arsehole within his personal relationships too
You will be cleaning up after an actual baby soon enough, don’t be fooled into cleaning up this man-baby’s shit into the bargain
