Interesting replies so far. Thank you, guys. I'm trying to see things from a womans' perspective and actually, it's not that difficult to do that because I know how it feels when someone is chasing you. Recently, some chicks were really persistent in chasing me.
On the one hand, it boosted my ego of course, on the other hand, I was a bit scared because I didn't know if some of these women would take it too far and do some crazy sh** in their obsession with me. Thank god, all of them figured out after a while that I was just not interested. I guess, some of them had thought that they could change my mind and regarded my lack of interest in them as a "challenge" but even the most persistent woman gets the message if you keep ignoring her for months.
On the one hand, I feel flattered and consider the possibility of giving her a chance since she must be really interested in me, on the other hand, there's a reason why I'm not as interested in her as she is in me and I'm not the type of man to throw my standards out the window just because I feel sorry for her or because I admire her persistence.
