Please no judgment

I been with my boyfriend for about 5 years and let me tell he you he was my knight an shining armor it felt like we have a beautiful 4 year old boy and I’m currently 12 weeks pregnant with our second but when I moved in with him that all started to fade he became a man I didn’t know , it started with a slap then a busted lip to bruises on my neck that I had to hide then the bruises on my arm that I had to make up a story to his mother on how I got them . When we went places I had to look down and if I even dared to look up was another story ...he constantly accuses me of cheating I NEVER have it’s an on going thing “He tells me if I ever find out something you don’t wanna know what will happen to you “ , He threatens me all the time about taking our son away if I ever try to leave him .. How can I love this man and be scared of him at the same time .... How can you hurt the person You say you LOVE and Can YOU do an say all the things to the person YOU LOVE I stayed because I love him and I hoped he’ll change and I’m facing reality that he never will and it kills me ! I have no one (but my mom) I no longer talk to my family I have no job no income nothing I’m so disappointed because I LET THIS ALL HAPPEN. My fault I feel disgusted with myself for painting the perfect picture to my mom making her believe he’s amazing I Came to realize maybe this is my life I choose to settle and I’m getting what I asked for.........
