I don't want to help my boyfriend clean the apartment.
Why don't you want to help your boyfriend clean the apartment?
He hasn't been taking care of my needs very well lately and I don't think I should have to help him.
It's fine to not want to clean sometimes. But since you live there you need clean up after yourself. Using this as a way to get back at your boyfriend for inattention is not appropriate.
I think if I don't clean it will make him take notice of me.
You should talk with your boyfriend and tell him how you feel. He may not understand that you feel neglected and need more attention from him. It would be good to be direct with him so that he understands the issues between you.
