Laboring in a hotel room 😞

My alcoholic husband was MIA all week drunk. On Friday he came to me apologizing that he has a problem and doesn’t wanna lose me. He went to work half the day Friday. Promised to be sober. I gave him a chance to be responsible for 30 min watching our 5 year old off the bus, after school(my mistake/my fault). I had an OB appointment. I got back and my son was crying that daddy hit him. I immediately realize how intoxicated my husband is. I ended up shoving my husband outside and telling my son stay inside. I told him he needed to leave or I was calling his parents and/or police to get him. He stood there and called our son a “fucking asshole”, blaming me saying I’m awful and let our son act that way. Our son had a field trip at school and was just exhausted. He was just being a normal kid. I ended up locking my husband out and calling his parents cuz he refused to leave. Well his brother and kids are living with them, so his wife called me back saying they weren’t picking him up and dealing with him. I felt so stuck and sad. He was pounding on the door and my son opened it and he tried to pull him outside demanding he go with him. I was able to get him back inside and lock the door again. I was fearing even walking to my car after. I needed help badly. Finally I packed a bag and went to a hotel with my son. I’m trying to navigate and figure out what to even do now. My husband isn’t welcome at the hospital when I finally go in. Baby is engaged, I’m fully effaced with contractions. I am a SAHM and don’t have much money. I think I want a separation from my husband. I can’t do this anymore. I don’t want my poor kids around it and I don’t deserve it. Things WERE getting better. He was sober for awhile. I thought he was changing around. I don’t know what happened. I’ve never felt more alone.
