Teenage relationship advice please!!

I love my boyfriend, we’ve been together for around 6 months now and he’s done nothing wrong, he’s cut girls out of his life because i’m uncomfortable with him talking to them which is what i adore about him, but recently he’s been telling me how i pay more attention to other guys and how i treat him like shit. But he does too, he’ll talk to a girl for ages and then realise an hour later that i’m there, and when he’s in a bad mood he can be really horrible. I told him that we both do the same things and that he’s only looking into the bad things i do to him and not the good things, whereas i don’t notice when he does all that stuff to me because i know that everyone has their off days and he’s not only going to be friends with guys. He shouldn’t be the only one allowed to be in a bad mood sometimes because it’s human nature and he can’t expect me to be perfect when he can’t be either, it’s impossible!! so i don’t know what to do and how to make him realise that this isn’t a one way relationship, maybe slightly a stupid topic but i just want the reassurance that someone has been through the same and it’s just a phase
