Fight with husband

So last night he kicked me out. But then after I left said that he didn't tell me to leave. This is not the first time this has happened.... it gets turned around on me. Keep in mind I'm 21w pregnant and it was,1am, I just parked down the driveway and stayed there til he came out harassing me so I went down the street to a parking lot and stayed there til 2am when he finally texted to tell me to come home. Mean while I'm just sitting there having a panic attack wondering what the hell I'm going to do with two kids and one on the way when he's not even letting me in our house. There's so much stress lately it's crazy.... does he not think about the baby? This might be the worst fight we've ever had but definitely not the first.. I just really don't know what to do
