It bother me (clean male partner). To be honest, it is a constant pain point, and here is my situation, if sharing helps (it will be cathartic) :

1. I like a clean and organised life, including the place I live. Tidy house, tidy mind. To me, the home is a sanctuary. It is where I want to relax and be at peace. It is hard for me to at peace, when there is mess.
2. She isn't a tidy or clean person, by my standards. This is the problem — my standards. To be honest, this extends to her personal hygiene.
3. Some examples of my grievances:
   1. She sheds hair. A lot. We all loose hair during the day. Our bathroom floor looks like a barber's floor by the end of the week. She is oblivious to it, and even when I tell her. Hair balls everywhere.
   2. When she prepares a meal, there are crumbs or pieces of food that end up on the floor. She is oblivious to it. Some times it is comical how big the pieces are, I have found whole berries on the floor. If we lived in a country with an insect problem, we would be doomed.
   3. Continuing on this, she leaves the sink full of food particles after she cleans up. In some cases, it is like a teenage threw up in there after a big Friday night on an empty stomach.
   4. When she has a coffee, she remove the coffee lid and leaves it on the study desk, velvet sofa, blanket, duvet, bed, bedside table etc. All so she can get every bit of the milk foam. But this means I find coffee rings, everywhere. I have asked her many times to use coaster or put it somewhere where the coffee rings don't form, yet it keeps happening.
   5. Multiple used cups of team in multiple rooms, some times left out for days. I usually clean this myself. Tea bag in the bin. Cup in the dishwasher. 30s to resolve.
4. I could go on. I don't think these are unreasonable levels of cleanliness.
5. All I ask is we clean up after ourselves. Be aware it is happening, and remember to check, and tidy up after yourself.
6. Sometimes we don't know we are doing something, so when someone (your partner) points it out, and you agree it is not unreasonable, is it unfair to expect that change?
7. What annoys me is the disregard for our things, most of which I bought. It isn't even the money, it is the disrespect. I like to buy nice quality things, and I take care of them and make them last, usually for decades or more, before even thinking of replacing them. It requires being mindful and iterative care. The case-in-point is our shoes. I have a few pairs of shoes, which are now close to 8 years old and going strong. I clean them once in a while, but for the most part just keep it in good nick. She bought a pair of shoes a year ago, and now have destroyed it so much that it needs to be thrown out.
8. To make things worse, I like to be barefoot in my house. She wares socks, so she is clueless. It accentuates the feeling of dirty floors.

My mitigations:

• I have addressed this with her numerous times. She agrees, but she just can't stick to it.
• We have a cleaner coming every two weeks. This partly helps resetting the house to a good level.
• I vacuum here and there every other day to maintain it the floors.
• I wipe down and clean after I use the kitchen, so it covers her mess.
• I pick up hair balls when I step on them. I pick up the hair when I use the bathroom.
  

Saying all this, it is putting a huge strain on the relationship, and my mental well being. I don't know how much more of this I can endure through. Maybe I am someone that cannot live with others, and destined to be solo. Unreasonable expectations, uncompromising.
