i am not going to specify the gender because it's all the same.
so if a person contributes 50/50 to the household expenses but doesn't pull their weight at home and not doing anything chores at home, can you be with them?
Honestly, I think a relationship is 50-50 including pulling the weight at home. Relationships work better when you're working as a team, however, I do understand the perspective of having one handle everything at the house.
