The thing I struggle with is how fickle women’s feelings are. Say she feels that spark on the first few dates but you say or do something to mysteriously and instantly kill the spark (even though you aren’t aware you just did), then you get the text the next day “something changed for me, sorry!”. I’ve experienced that more often than first date rejections.
Unfortunately, no one has come up with a way to make post first date rejections completely vanish. A lot of times there's a learning lesson to help us improve our odds.
For instance; when I'd get a text from a gal (and if I was free at that moment) I'd text right back. Although I'm not fond of calculating games, I've found that my 'pay out' is much better if I let a text sit for a while. Although there's a group-think here that you should never text unless setting up a date, this advice is about as counter-productive as over texting. Through trial and error, I've found the over-all 'sweet spot.'
Another thing that I've done is to look through previous e-mails and text exchanges. Sometimes, we can find that "ah ha" moment and if it happens more frequently at a certain moment, then we can learn "what isn't working" and modify.
