I'm aware of having abundant mentality and nexting a girl when she rejects or turns me down. Although sometimes I wonder if it's because the the girl is not comfortable with me yet or wants me show a little more investment.

I've asked out a few girls that have showed ioi but for them to only flake on me or dismiss my invitation. I see them again the next day(we attend same university) and they are still showing the same IOI and still receptive to me. I feel like they want me to fight for them and prove I'm not just some fuckboy.

You guys have always frowned on chasing so I'm asking, how far should I chase and invest until it's not appropriate for me to.
