Abusive relationship & pregnant

I’m 4 months pregnant & my bf is verbally & mentally abusive when he drinks.

Tonight he is raging mad bc I told an old guy friend happy birthday on twitter. He literally beat a complete hole through our bedroom door. & told me to get out of our room

He also pays all of the bills bc he tells me not to help but throws it in my face when he’s drunk and makes me out to be a POS using him.

The day we were going to find out the gender I told him my mom was coming w (she’s a first time gma) & she had asked last min so I forgot to mention it to him. Well, he was so pissed off the whole day. He was trying to throw it in my face that his mom was probably upset (she has 2 grandkids) but I told him, if he had wanted her to go why did I have to invite her? Why couldn’t he have? And he screamed in my face all day that I was selfish. (Ruined my whole day of finding out my first baby’s gender)

He also always makes a huge deal to even grab my phone and will make sure it’s flipped upside down if I ask him to hand it to me. He makes me feel like he thinks I’m a whore or something by saying things like “I’m not looking at that dick box”

Ect... I’m so tired of being treated like this but I’m so afraid of the process of us going to court & him getting his right of some custody. Y’all I can not share custody w a newborn baby 😭😭😭😭
