How to go about this with court...

*Trigger warning*

While I understand the severity of the situation, please be kind.

Over the past 5 months, my husband has become more mentally/ verbally abusive to me than ever before. I say ever because everyone has weak moments and says something they wished they hadn't.

It's gotten to the point that I've decided that I dont want to be with him anymore. He's calling me horrible and awful things in front of our 5 year old daughter which kills me. (Examples: Isn't your mom fat and gross, call her cholesterol, worthless mom etc) I remove her from the situation and dont react or respond. I told him last week I wanted him out. That I dont want to be with him anymore. That I want a divorce. He told me, has sent messages and I have a video of him saying that if I try to leave, call the police or take our child and leave that he will kill me. I 100% believe he would. His rage these days are unreal.

I know about orders of protection, that dont matter because I had a relative have one against her ex husband and he murdered her anyway. I dont want to live in fear. I dont want to have a piece of papto "protect me". I dont want to have to sit in fear. We live in Tennessee if that's any help.

I have no family or friends really (just moved here 5 months ago) and no one "back home" either. His family that's here is a "blood is thicker than water" type deal and even if he is wrong...which I've confided in his sister, and the response I get is "oh he doesn't mean it". What can I do to get him away. I dont want to and shouldn't have to leave MY home that I pay for and uproot mine and my child's life on account of him. Suggestions please.
