How can you tell that girls don't like you gradually

How to see that girls don't like you gradually, from the following points, 1. I can joke with you casually, and I can face your jokes calmly without thinking. I can't dress up every time I see you. It may still be exquisite, but without those careful thoughts, many details would not be done so well. 3. No longer the silly little girl in front of you who can't do anything or often makes mistakes, but a very comfortable and normal person who makes you feel like your work partner. 4. There will be less and less contact with things other than work, and you will never hear other people's comments on you again. I won't advise you anything, basically just look on coldly and treat you as a stranger. It's very polite and strange.
