Boys love us (girls). They adore us. Without us whose feelings are they going mess with? They can't talk to guys they would to girls because they think it's gay and being gay is gay. They talk to multiple girls at one time and tell them the same thing. They don't care whose feelings get hurt as long as they're happy. And the worst part is, we fall for them even though we know everything. 
You have to kiss a few frogs to find the prince though.
When finding the boy that treats a girl the right way, that's the one she needs to hold on too. The worst part about that is that we want the boys who can't treat us right.
