Be with someone who bring up my past everyday for the past month?

My boyfriend of 6 years who I have a 5 year old son with, has been bringing up my past every single day for the past month. According to him, I gross him out and he doesn't want to be with me anymore because of my innocent past!! It all started when I decided to leave his parents house for good when I found out he was searching up a porn star at work. I got over it because I guess it's normal for guys to watch porn, but it kinda bothered me that he had to google search her and was looking at her pictures. I first I thought it was a girl from work, but then I saw names of videos of her like anal sex. So while I left him during the weekend, we began talking again, but this time all he wanted to know was my past again. We discussed our past partners and he says that he was grossed out by it but had to move on from it because I kept forcing to be with him, whatever dude. So he decided to ask me again who I slept with? What's his name, was it the guy he saw on my Facebook? Was I fucking those guys? Why was I talking to them? How many guys did I sleep with? Man he was just digging up my past just like digging up dirt with a shovel. I didn't wanna answer any of that because all that was before I met him!!! and he began coming up with lies to make it seem like they were real. For example for some reason he believed that I compared his dong siZe to someone else. WHAT THE F?!! NEVER IN MY LIFE DID I EVER SAY THAT! Where did he come up with that!? Who knows but he swears I did. Anyways. I didn't wanna answer anything but I ended up answering his questions because he made me believe that he would get over our issues if I was just honest with him about it. So like I told him before I was with 4 guys way before I met him, and told him their names and confirmed some suspicions he had that were actual true. But by doing that he is now repulsed by me, he does t want to be with me because I'm gross. Yet he still has sex with me and I have up my bootyhole for him Because I thought it was going to make him closer to me but nope. And so for a whole month he has been distancing himself and avoiding my presence. Which makes me feel so sick because I don't think 4 guys is anything bad at all. There's girls who slept with so many other guys and have a boyfriend who don't give two shits. There are dirty girls in this world but I am not one. Either way my past is my past. And ever single day he says passive aggressive things referring to me exes, and conversations I had with guys way before I met him. He's so obsessed with my past and cares about my exes way more than I ever did. We fight everyday because he can't stop thinking about my past!!! His parents are sick of his ways of thinking and they understand that I had a past because I was a teenager! And they know he was a past too so they don't understand why he makes a big deal of it. He says that when I left him, all those memories can back yo him, all the memories of when we broke up a year in toghether and when he got anDUI after going out to party the day after we broke up. He had deactivated his Facebook and read all his old message from the night he got out of jail. He says that if I never left he would not be putting me through this. Is it my fault for overreacting and leaving? Because either way, no one has the right to judge me for my past, especially a past that was so innocent for gods sake I was 17 last time I had a boyfriend before I met him. And I met him when I was 19! So hard for me to give up on him like he is with me.
