I had a very steep learning curve four years ago, which meant now through rejection in the early stages I just learn to walk away and never ever look back.

Why is it having that mindset means those girls who you gave it your all too, who walked away suddenly the tide has now then turned and they become massively attracted to you?

I also literally feel no interest in them, and they'll put obvious effort it. This is usually those who know I liked them before and they brushed me off despite them initially liking me.
