minny with great advice on never chasing them. even ignore them at times. let them think you are busy or focused on someone else. every single girl/woman i have shown interest in "too much" in the beginning never worked out.
unless she is flirting back or texting you out of nowhere, she is not into you. believe me. i have learned that the disappointing way a lot.
also, life is not a porn movie. most women are not just looking to be pounded out when at the grocery store. this is not meant to be so literal but you should get my point.
