Oh boy, this sounds like an interesting thread so heres my two cents.
Personally, Ive read so much BS PUA/Red Pill crap on what to do when someone specifically a girl doesnt respond to your text messages. The only thing Ive read that makes sense to me is to just brush it off and find someone else who actually wants to be around you. It sure as hell beats chasing after someone who gives no fucks about you, thats for sure. Lol
