I don't need to pay a therapist to give me crap. I have a roommate that does it for free". ~ Ally McBeal
Sometimes it's just not possible to divide space between the two of you for everything; refrigerators, microwaves, bathrooms spaces, etc. Women tend to be bothered by unclean or shabby roommates more than men because most men tend be messy in varying degrees so they cope up with each other's mess. More women are comparatively cleanliness freaks because they have been brought up to perform household chores with perfection. But, if your female roommate is so messy that her habits are getting onto your nerves, keep your cool. There is a solution to every problem and you can totally deal with such a roommate. I am guessing you have already tried talking to your roommate about dividing responsibilities to clean the house and that hasn't worked and now the messiness is intolerable. Nagging never really helped anyone.
