What should I do about my daughter?

So daughter 21 afraid to drive

Can’t get to work but bf mad she has no job and spends her day in the room
I hired drivers at $60 an hour for her and her brother 18
Bf kicked his kids out at 17
Wants her to go
So much so he hasn’t spoke to ME in 3 days because I said I will drive with her until she gets her license
When is enough
When do you stop doing and let them fend for themselves
He said I want them under my thumb
Well kinda
They cook and clean and put dishes away and do laundry and stay in the rooms
No drugs no danger no drama
I’m lost
I can do it on my own again
Just was hoping this guy was the one that was going to stick around
