Look into getting counselling.
Look at doing the Freedom Programme You can do it online.
Speak to Women's Aid.
Buy the book by Lundy Bancroft Why does he do that?*

Have as little to do with him as possible, go NC or grey rock.
You need to stay strong for your baby.
Try and build yourself up as much as possible with supportive friends and family.
