what to do with my relationship with my boyfriend?

my boyfriend broke up with me last year right before our two year anniversary and told me he was confused and needed some time. I did everything for him, I bought him everything he wanted that I could afford I always had dinner waiting for him I took care of the house by myself he refused to help do anything, would get mad if I didnt wash a particular item of clothing and ignored everything I did do. I thought I was doing things right, and I felt like I just wasnt good enough for him. shortly after I found out he had slept with his ex girlfriend and she was frequenting our apt. and I was devastated, what did she have that I dont? what makes her so much better than me? well after a few months and a lot of messed up stuff I gave him another chance because I just wasnt ready to let go. well we’ve been back together for a little over a year now, and I cant let it go I want so bad to forget about it but he never fessed up to what he did. I offered him complete immunity to tell the truth just so I could move past it, I just need to hear him say it. but my problem is I dont know if this relationship is something I need to be putting myself through. he is so disrespectful of me, (ex. needs to always know where im going who im with, but when I ask says im not his mom and he doesnt have to tell me). we’ve been through a lot, I got pregnant which he was less than happy about, refused to go to doc visits with me had no interest. I lost the baby and was heartbroken and he was temporarily supportive but now just says I need to get over it. He is horrible to me and all of my friends hate him, and everytime I think im gunna leave he knocks me down a notch like im nothing and hes so manipulative. I want to leave but am scared I might make a bad decision or will always be alone…he’s made me feel worthless.
