How do you get along with a perfectionist?

I remember I had this gf who was a total perfectionist. I would visit her on weekends and I would always find her cleaning the house to the last detail. Sometimes it would take her 2 to 3 hours just to clean the windows. She wanted to do an immaculate job, and she was good but man! she spent hours and hours cleaning her place. One time she asked me to help her weed her garden, as I was doing it, she pointed out to me the steps she always took to get the job done. First you have to wear this gloves, then have a mask, wear these boots, she had all the gadgets in place. I asked her, do you have a written manual on how to weed the garden….you know, she got pissed. One thing I really appreciate about her is that now I put more attention at organization, but at that time it was driving me nuts.
