Honestly speaking, how do you expect your boyfriend to be okay with you if you lied more than once over little things?

My boyfriend and I got into a fight because he says that I'm lying to him. One thing for sure is that i love my boyfriend veery much and no I’m not cheating on him. if that was the case I would’ve been single. But my boyfriend says that I’ve lied to him more than once and he even put me on the spot on one occasion. Things he says that I lied about are, saying that I posted him on social media (atm we were joking around or so I thought cause he said that he accidentally posted me on his story just playing around, and well I told him that I did too, but in reality in my story it was a cartoon character that I said was him), when we got into a huge argument and we didn’t talk for days, I changed his contact name after I saw that he changed mines and so he said that I lied to him cause I kept changing the story. He says I change my story a lot, it’s just small things that he says I lie about, small unimportant things. I've always been real to him about bit things. How can I answer this question to him? I really want to be with him and he does too, we gone through so many obstacles for this be the end. What can I do? What can I do to prove to him that I can be better. I know he hates lying. How can I show him? How can I answer him honestly this question tomorrow when he calls me. Help please
