If girls like guys who treat them like ***maybe that's why I'm single.
Some girls just aren't as great as you think they are just because they're pretty and not mean to you. Remember that, painful as it may be to hear, to some women being nice to
all men isn't their true personality, it's a defense mechanism. And some are legit nice but they just simply don't find you to be relationship material.
It's important to remember that just because they're dating an *** doesn't
necessarily mean they're wrong for each other. Different people value different things in a partner.
Painful to hear about a friend and I won't be offended if you disregard it or disbelieve it, and maybe I'm wrong. Clearly I don't have all the details.
But TL;DR -- keep your chin up, trite as it may be, there are plenty of fish in the sea and they're not all gonna bite on your tackle.
