I'm angry at my girlfriend for not cleaning our apartment as much as I do.
Why are you so angry about that?
I think it is not fair for her to clean less than me, I'm working after all
I'm sorry she's not doing her fair share. People need to share housework with those they live with. Sounds like she needs to help out more!
I agree.
You should tell her how you feel about the cleaning so that she knows she needs to do more.
