I guess people often forget that love and relationship is a two-way thing. Yes, a guy can break a girl's heart but then we oversee that us, girls could do the same thing too, maybe worse. It's scary to think we have such power to destruct another person. In a relationship or falling in love, then without thinking (or doesn't want to) we hand over ourselves wholeheartedly at our own will to the other putting at stake that one precious thing that we held on to so dearly to us before - our heart.
