Advice ? Rant ?

So I’ve been with my current boyfriend for about 6 months , almost a year since we met but he’s been in a previous relationship for like 8 months with this other girl and I guess she kind of messed him up but he’s been working on himself and stuff. But I just can’t get him to understand that every time we argue about the SMALLEST things that it’s not a big deal and everyone argues. Our arguments aren’t even serious. Like he hates that he hurts my feelings sometimes and I understand that but he doesn’t do it like in an abusive way, I’m bound to get my feelings hurt sometimes! I overthink or could interpret his tone in a certain way and feel bad for like 5 millisecond. And it definitely could go both ways where he could misinterpret something I said . But 95% of the time . We are laughing and happy and he never does anything to intentionally hurt me or make me feel bad and he just doesn’t wanna accept the fact that sometimes we could feel a type of way , and argue and get mad and I could get an attitude, he just thinks that I “deserve better” and he’s not doing that for me and no matter what I say, he ends up saying something like “you don’t have much of an experience to compare your happiness “ he thinks if I had a lot of experience then he’d feel better about my judgement about him being a good boyfriend. I know he’s broken and he like needs to feel valid and sure of everything but it’s so hard to convince him otherwise and at times we do almost break up cause of this because I know the depth of my own happiness and I hate that he thinks I need experience to validate my own feelings and judgment. Idk , any thoughts or advice or whatever? Am I wrong ? Do I not know what I’m talking about ??
