I am not be sure to be honest.
I think it's because I played the oblivious card.
I played the I totally don't care about you, you are not good enough to even be on my radar card. (I was a-hole I admit it). Which seems to drive some chicks absolutely wild. I guess they feel like they have something to prove.
Also I was fairly physically attractive at the time. 6ft, 220lbs of muscle not bad for a 18 year old back in the day, tattoos and piercings. I hustled on the side, so I had money to flash. All the typical stuff young chicks dig and think matters, nice car etc.
One of those 2 things or a combination of both.
Regardless I don't have or use either tactic anymore.
But as an old man giving a young man advice. Play the ignore card. Don't show any interest at all. If they ask you to do something just say something like "eh sure, whatevs". Easier said than done, and it makes no sense at all but it works.
It doesn't work as an old man. I ignore em and they could give less of an "eff".
The problem us single old men have is they want to use us for money. They don't mind teasing and insinuating, but they just want the money, they don't care about a relationship or going through with the flirty banter. But that's why I stopped dating anyone under 30 years old (I'm 41).
Last chick I dated under 30, was about 6 months ago. She was 22, don't get me wrong the sex was great, but she was only after money. She didn't give a p00p about me otherwise. Soon as the gifts and spoiling slowed down, trouble reared its ugly head, to no surprise.
