Relationship advice

I don’t know what to do about this situation and I hope you have some advice for me.

My bf and I have been together over a year and we live together.

I have been having an issue with how my boyfriend doesn’t clean up after himself often and I feel like I’m constantly picking up his clothes, throwing away his trash, cleaning the bathroom after him, etc.

I’m so tired of it. I have tried talking to him about it and he says that it’ll change. But it hasn’t.

We both have full time jobs. And I am tired after work and don’t clean as much during the week. I usually do deep cleans and laundry on the weekend.

I told him if we both clean a little everyday , it would help a lot.

But he doesn’t. And it feels like I’m dating a teenage boy instead of a man in his late 20s.

Does anyone have advice for me??

(Also, my ex was like this as well but I didn’t live with him. But his apartment was always a mess and I cleaned it up. Are all men like this or something?)
