Relationship issues

Hi guys I’m seeking advice. So me and my boyfriend relationship was pretty healthy in the beginning, he was nice, supportive, and a gentlemen. When i first started texting him it wasn’t nothing going on plus he was talking to another girl but they all of sudden stopped. He would add me on instagram while talking to her (talking stag) but i would block him or remove his follow. Then months went by and he finally had stop talking to the girl. He added me on instagram and i accepted it, then i would text him flirting. I texted him out of wanted a sexual interaction because i had not done anything sexual in 3 years. So i had sex with him but he was a virgin and i told him i had one body. 2 weeks went by and he asked me out, i said yes but i felt confused because it was too soon for me to feel love and i thought he was cute but i wasn’t very very attracted. Anyways months went by and we had hit about 4 months and he found out i had 2 bodies before i did anything with him and he got mad because he said he was the 3rd and felt lied to and felt that it wasn’t fair. 2 months go by and he has changed so much by putting less effort who make up when we argue. He also had become disrespectful calling me disgusting and always mentioning my body count. Overall i don’t know what to do pls give me advice.
