Fight for it or move on? Marriage edition

Alright I need advice,

So I have been married to my husband for two years now, married for one.

I have children from another marriage.

He’s military too for purposes of this post.

When we got together we were toxic. We were younger and dumb. We wanted it to work when it shouldn’t have. We found out I was pregnant February of 2021. We got married (was engaged before finding out) and moved to our new duty station. We were great but he started drinking alcohol way more than I wanted him to. There was red flags and I KNEW we didn’t need to be together but we did it anyway. The drinking got bad and there was an incident where he punched a hole in my sons wall and blamed him for it. I took my kids and left that night. Then a couple of months went by after working it out (so I thought) I had just had my youngest baby and I was at a friends house and I wanted his help to come get us because I wasn’t supposed to lift the car seat.. well I called him for help and I found out he left my 5 year old at home alone to buy alcohol. Flash forward after forgiving him again.. New Years last year.. he was out drinking all night and I was home with the kids and when he came home he passed out and I tried to wake him up SO MANY different ways but he passed out drunk and I couldn’t wake him.. well (I know I was wrong butt.. ) I slapped him to wake him up bc I was so mad and I needed him help, well he woke up and kneed me down while holding my one month old and punched me in the head.

Again forgiven. He just a month ago got drunk and fell while holding my youngest (6 month old) and dropped him and he hit his head and he didn’t tell me!! I got home from Walmart (I was gone for 20 mins that’s it!!) and the baby was passed out, didn’t think anything of it.. well he went out with his friend drinking and I was home cooking and the baby finally woke up and he had a huge red spot on his head, and I didn’t know what was wrong until he started throwing up and I knew something wasn’t right. When I called him all he said was “I think he hit his head on the ground, I don’t know.” When he got home and told me the Truth and I shoved his head into the brick wall because I had to take the baby to get a CT scan… I am by no means perfect but I don’t lie, or cheat or have an addiction or anything crazy… there’s TONS more not entirely alcohol related.. he’s deployed now and I just found out I was pregnant (yes it’s his) but should I use this 6 months he’s gone to work on the relationship or become independent and get out? Because I don’t know what to do…..
