Do i cut my dad off?? 😔😔😔 plz read, need advice

I love my dad but we have been through so much.

At 15 I had to testify in court against him for choking my mom in front of me which broke my heart cause my mom lied and so I had to go up and do it or they would have taken me to jail they said. The day after this my mom filed for divorce and my dad blamed it all on me. This went on for a couple years and we finally got back our relationship, which was never great even before the divorce (he wasn’t actively there financially or physically, and I grew up seeing him be mostly emotionally abusive towards my mom but also sometimes physical). Anyways I love him and I have forgiven him for everything.

Until recently. I’m now 22 years old and 7 months pregnant and his attitude towards me has picked up again. He would never sign the divorce papers and my mom ran out of money trying to get him in court, so legally they’re divorce is still open and the house that is in both of their names I currently live in with my little brother, (his gf and baby live here too) my mom and her boyfriend, and just a couple of months ago me and my boyfriend moved in as we moved back to Utah from out of state, and we wanted to save up some money for the baby and getting a house.

Well my little brother hates me because he doesn’t work, neither does his gf and they just mooch of my mom and dad. They have a 2 year old son, she is 20 and he is 17!!!! So I would say dude you need to get a job, or id tell his gf to clean up her and the babies messes which she would just usually leave for my mom so my little brother just told my mom he was moving to North Dakota with his girlfriends family. My mom is fine with it because it’s a huge weight off her shoulders and he is 18 in August. He went to my dad and bitched about everything so now my dad is pushing the sale of this house because “my brother is a baby and should be able to live in peace til he is 18” ( no one kicked him out or told him to leave, just asked for him to treat the home with respect and get a job, but he threw a fit) IMO when you have a kid, you no longer get the privilege of acting like a kid.

Anyways I called my dad and I was like why are you trying to push the sale of the house? I’m having a baby in two months and we planned on staying here for a couple of months after her to save money (MY DAD NEVER PAID BILLS FOR THIS HOUSE, it was all my mom and my grandma, he was always spending his money on drugs and his friends), and my mom doesn’t deserve this after doing everything on her own. And my dad goes back to blaming me for everything. Telling me I ruined his life, telling me to go to hell, calling me a bitch..... I don’t care about the house at this point we can get our own place ASAP, it’s just the idea... he won’t apologize and he hasn’t talked to me since, won’t answer my calls or anything. Also he said I’m lucky he hasn’t killed himself or any of us yet.... meaning me, my mom or her boyfriend, and told my mom he planned on killing her......

I love him but I think I need to cut him off... as well as my little brother and his family..... any advice? This stresses me out so bad and makes me feel sick to my stomach cause I never did anything wrong to any of them just stuck up for my mom... 😔
