Abusive Husband Who Has Been Absent For 4 Years Suddenly Demanding To See Daughter

About him: He was abusive, I'd been sent to the ER multiple times, he even got kicked out of the military dishonorably for abusing me. He went to jail after leaving the military for hurting me. And never came back. He's been living with his parents for all these years. He didn't have a job that whole time until recently. Now he is demanding to see her.

We didn't get a divorce. I was busy picking up the pieces. I have had jobs. I have my own apartment. I take care of my daughter. It's been only me that has this whole time. He left when she was about 6 months old. I've taken her to doctors, pediatrician, dentists, daycare, etc. I feed her, provide for her, etc. Only me.

He told me recently he's gotten this job. For a couple months now he's been sending money every other week and demanding I sign online divorce papers. I want custody, I want him to not hurt her, I want supervision during his "parenting time". I want child support and the owed child support for all of these years.

I need help on how to move forward. I would love to divorce this man. I'm pretty sure I can get waived fees doing so. I also want child support. I don't mind her having visits with him. For the first year or two after he left I tried seeing him with her and he ignored me or blocked me. I did have a restraining order though, so it makes sense legally? I think. But the restraining order was only a year.

He never asked to see her on her birthday. Or any holiday. One year he even got her age wrong while texting me a belated happy birthday to her.

We both moved on with other partners. Still legally married.

He keeps saying she "knows him and needs him" she doesn't recognize who he is, obviously.

I have let them video call. And I have met up with him bringing her so he can see her. I even let him into my home around Christmas time to give her gifts. He brought clothes that were 2 sizes too small.

He's truly an awful person, he hits his parents, he beat me, and he can be extremely manipulative. If he wants a relationship with my daughter, I want to know how to move forward so I can set it up so it will be safe for her.

His new job pays more than my current one does and I'm scared he's going to take her.

I guess that's a summary of the situation now. Can anyone help please?
