I’ve heard of this concept of trying to get the other to say no, but mostly from guys. They don’t always want to say no since girls take a no very personally and many girls will be hurt by a no.
Guys are made of tougher stuff – they can handle a no gracefully. Don’t worry too much about him and JUST SAY NO. There is nothing worse than going out and sensing from the start that your date is completely not interested in you. Waste of time, waste of money.
