So he left us

But I probably should have left him a long time ago.... My husband and I are high school sweet hearts, we met at 16 when I moved to this state. we've been together 6 years and married for almost 2. We have a son who is almost a year old and I am 11 weeks pregnant. Well long story short about a month ago he tried to kill me, he choked me while I was screaming "I'm pregnant please stop" and then I woke up to him saying "Damn I didn't kill you?" I left and we talked things out and stupidly came back with a promise he'll get closer to God and he'll go get the mental help he needs. We fought a couple times but it didn't get physical again until this morning. (of course there was the emotional abuse) but this morning he like literally snapped over nothing and said he was gonna kill me again and a bunch of other stuff. I'm a stay at home mom so I don't have an income and he said I need to leave "his" house, and "his" car since it's in his name. My pastor and his wife know about all this and told me last time to start documenting things, so I have recordings of parts of our fights without him knowing. For example I have him saying he hopes I crash and die and me and the baby die because he never wanted it. Is that and the abuse towards me enough evidence so I will get full custody, I know I need to get a job and a place to stay, but with that I can get full custody of my son and the baby I'm pregnant with right? Any tips on what to do?
