You are unlucky enough to be his current target. I don't mean to scare you, but only to emphasize the possibilities in giving partial custody to him. If you are fortunate enough to be able to get full custody, you're lucky. In many states it is very difficult to obtain full custody, even when abuse can be proven. It is true that this might anger him further.
Abusers can be very unpredictable.
But, allowing him to stay involved in your life will almost certainly create a situation where he can continue to abuse you and affect your daughter. I would go even further and suggest that, after you get custody, you try to leave the state and get as far away from him as possible, if you can do that legally. If he says he has changed, be very skeptical. Abusers can change, but it requires a lot of time and hard work. Most abusers can't change significantly without professional help.
