OP, you would almost certainly find that your anxiety evaporated and your confidence returns if you were not living on eggshells.
Was it 6 years ago when your Dd was 12 that he beat you black and blue?
He is currently both emotionally and financially abusive. He uses emotional blackmail and money to keep you downtrodden and in a state where you silently beg for the next time he love bombs you.
His treatment of your Dd is truly horrible. Poor girl. How would you feel if she was in a relationship like this? Because in truth you are not showing her what a healthy happy relationship is , and by allowing her to see that you have prioritised an abusive man over her , you risk that her own depleted self esteem will end up with her enduring similar abuse.
Has he been physically abusive at other times?
You can leave him but it isn’t as easy as ‘just leave’. Needs thought and a plan.
Where is your son now?
Do you have family you could stay with? While you sort things out?
Women’s Aid can help but are inundated (sadly).
Can you get access to counselling to give you some emotional support professionally?
