Why don’t I have enough self worth to say goodbye to fuck boys??

I’ve been hooking up with the same guy since the end of October. His name is Jon, he’s adorable, best lover I’ve ever been with, the most amazing kisser in the world, whenever we are together we can’t stop laughing. I’m totally head over heels in love with him and he’s been telling me he loves me for awhile now. BUT he keeps playing this shit where he says he can’t date me until he knows he can trust me because he’s been hurt by previous exes. Now at first I was understanding because I just got out of an abusive relationship myself. I wasn’t in a rush to be official with Jon because I already knew how I felt about him and I thought I knew how he felt about me. But now every other weekend he’s blowing up my phone about how he can’t trust me and it’s obvious that I’m talking to other guys when I’m not. He freaked out at me because apparently my bumble account was still active even though it’s been deleted from my phone. Hell, he WATCHED me delete it from my phone! Then he was saying that the photos on my bumble profile were from after we had started hooking up. His evidence was that I posted one of the same pictures on Instagram on thanksgiving, so he was saying it was obvious I was on bumble around thanksgiving. But I had posted an old photo of me and my dog on thanksgiving because it was her birthday. I literally sent him a screenshot of the photos in my camera roll saying they were taken back in September. He’s still pissed. So I took screenshots of me redownloading bumble, signing in, and showing him that the last message I received/answered to was October 5th. AND HE’S STILL MAD AT ME. I don’t know what else to do. I’m so fucking tired of having to “prove” I’m not with anyone else. But I love him so much and I don’t want to lose him. It kills me that he doesn’t trust me and that he attacks me like this. I just feel like it’s a projection on his behalf. What else can I do???
