Idk what to do or maybe im just scared of reality

Im turning 20 in a couple days my bf is going to be 23 in a couple months, im 29 weeks pregnant and my "S/O" treats me like im nothing he hasnt touched me since i became pregnant... he tells me horrible hurtful things when we get into arguments for example we recently got into an arrgument n he said "I dont even like you anymore you should leave" n its been replaying in my head ever since, he tries to control me with everything hes a great manipulator i want to leave i know itd be best for me n my child but i have seperation anxiety and it feels so hard to walk away we been together for almost 5 years. I feel like im in a hole n im just digging deeper instead of trying to get out. I just need someone i can talk to who wont judge me n can hear me out.
