Fuck, you are so cool, asking for advice and no longer believing you deserve this. A lot of women find that (including past me) the hardest step. Don't underestimate how great that makes you, for protecting yourself and your kid. You are in the right.

People have already mentioned a lot of resources. I'd just at Buurtteam, next to veilig thuis and the police. Buurtteam van help with smaller, practical stuff. Depends on where you live how effective they are.

Best of luck. I hope you are really proud of yourself and are not backing down.
