MEN ARE STUPID!

so me and my boyfriend are in the best relationship ever and we hardly have arguments but when we do...he accuses me of cheating WITH NO EVIDENCE OR ANYTHING he just gets a feeling of me cheating out of nowhere. This is the third time and I'm really getting tired of it but I don't want to lose him. He doesn't even apologize or anything he just comes to my house uxpectedly and kisses me and of course ladies, I take him back. I just don't want this to keep happening...thoughts???
