Vanilla,
I would say just try your best to ignore it if everything else in your relationship is great, but it sounds like its way too much to bear and it sounds like he won't take a hint and clean it up himself.

Perhaps you can ask again and relay to him how much this is hurting you and that you feel like he doesn't appreciate what you do. But be sure to be super nice and no nagging (not saying you are a nagger, but some men look at it as nagging)

Another suggestion is to stop doing other things in the house (cooking, grocery shopping etc) and spend that time cleaning. When he asks why there is no dinner or food in the house you can say that you had to spend that time cleaning up his mess!

Maybe you could do a trade off....tell him that every time he cleans up you will do something for him that he likes?

I hope this helps and good luck with everything.
