When a girl says 'maybe' to a date does she mean no? Watch
This works best if you have more than one woman in your life. If you don't and you want maintain your integrity, just tell her later that you aren't feeling it any more.
If it comes to the point where she says no to you, you've let yourself lose all attractiveness in her eyes. It's better to push her away and pull her back later, than it is to let her push you away. In the latter case you are a rejected loser. It will take months for you to recover your value in her eyes, and most probably you will lose interest or dive into the friend zone.
Depends how she said it. If her tone was outrageously flirtatious and she winked, hoisted up a tit and licked it, then she might have meant yes.
It's an obvious "no" then
