Nothing new about this. Women have always done this. It's just a part of the dating game. Means nothing. If she goes out with you and you both have a good time,win/win. If she goes out with you and the way she acts causes you to never want to take her out again,once again it is win/win because you quickly found out you have no interest in her.
True story. Years ago I had several people tell me that a girl I knew casually was going to really suck up to me because she knew I had concert tickets to see Elton John,and she wanted to go. She just didn't want to go with ME,but was willing to make that giant sacrifice if necessary. One of the people warning me was her sister.
So I took the ball and ran with it. We ran into each other at a party,and with her sister and everybody right there to listen,I asked her if she would like to go see Elton John with me,because I have a spare ticket. When she said "Yes,",I told her there were conditions. She had to promise to not pick her nose or fart in public. Ok,that locked her jaw a little,but she still wanted to go,so I took her.
When I got to her house the night of the concert,she came to the door wearing orange corduroy jump suit,a pair of Mickey Mouse sunglasses,and had dyed her hair green. This was in the 70's,when green hair was more than sorta unusual.
It was all I could do to not laugh out loud,but I managed to hold it in while looking down so she couldn't see the look on my face.
We got to the concert,and were having a good time,and then I looked over at her to see if she was enjoying herself,and she stuck a finger up her hose,raised a haunch,and let one rip.
I laughed until I thought I was going to puke.
We went out a BUNCH of times after that because we enjoyed each other's company,but there was never any romance at all. She has even left other people she was on a date with if they got boring or pushy,and would come looking for me to go drinking with.
To this very day she and I are very good friends. She has even called me and told me if I got too sick from the chemo to clean the house and take care of myself to let her know,and I could come stay with her and she would take care of me. I didn't ask her,she called and offered.
