Im so lost and hurt

My baby was born 12 days ago but ive been feeling this way since before he was born. I may be depresser but its not because of him and its not about my pregnancy. My boyfriend and i have been together for 3 years and finally got our miracle baby after trying and trying...and after 3 miscarriages. We live together.....but i guess i live with him. 2 years ago he bought his first home and we moved in it together. I still call him my boyfriene but i guess hes not even that anymore. Hes been sleeping on the couch for the past 4 months; at first his excuse was its because of his religion (muslim) he converted his religion a few years ago. But i knew that was just an excuse. In the past hes been abusive towards me. Physically....mentally...and emotionally. It stopped during my pregnancy although he did push me a few times during it and hes slapped me in my face. I feel stupid typing this because i know.....why am i with him? Hes my first love....my first boyfriend. Im 19 & hes 25. I dont have any friends anymore, i talk to no one, i dont have any social media, and i only use my phone for phone calls and glow. I make him dinners and breakfasts all the time...the house is always clean. Im an amazing mom. Ive always been so insecure, but hes made me feel my alllll time low about myself. His exes have never gone away.....they always seem to pop up; he has 2 exes that are still his friends. They dont hang out but they talk once in a while because theyre his friends....i cant stand it!!!! Because i know theyre still in love with him. And i know he knows that too. My "boyfriend" works 6 days a week 3pm-12:15am & he only has sunday off. His car is being fixed so hes been using my car for the past 2 months. Before the baby, I would drop him off to work....go home or run errands til his lunch break at 5 then go back home and later on pick him up from work at 12:15. He likes to sleep til about 11 then he runs to the gym quick for about an hour then comes home to shower & we would leave at 2 and be at his work by 2:30/3:00. Now i stay home because the baby is so new and i dont want to take him out of the house so late to get his dad. Anyways, my "boyfriend" and i havent been working out. Its like theres nothing between us anymore, but we have a baby together. As stupid as i sound, im so in love with him but i know im stupid for it. This just isnt the way i wanted things to be. Now he tells me he wants me to move out & that i have to leave my son. He tells me i can call the cops and whatever lawyers i want but i cant "beat" him. He calls me broke and says he has all the money so i cant do anything. I tell him, there doesnt have to be anything between us but i dont want problems like that. I tell him i dont want to get court and cops involved like that. I tell him for the sake of ourrrrr son that i want to be civil and handle it maturely. I asked him why would he want problems like that.....he doesnt say much. He tells me that i cant take his son away from him & i tell him thats not what i want, i would never want that. Thats spiting the child not him and i dont want these kind of problems. I just dont know what to do
