My bf is really messy and it’s bothering me

I’m a neat freak to the point where it gives me anxiety to be in a messy space, especially when it’s my own— my environment really affects me. My bf is so messy and he stays at my place a lot and I don’t feel like he respects the fact that I like to be neat (he knows this). I understand people have different living habits, but I’ve told him a lot and I’m getting bored of it, I would really appreciate it even if he just helped clean up after himself— what should I do?
