you should not told her in the first place, even u chosen her there is still thorn in her heart.

u might think you are so great and cool, when u said u want to break first then only pursue another girl.

but to me you are not, how much time you spend with her already ? did you know her deeply in person ? if she really suitable for you ?
you are not sensible enough to play your life with, crush is a crush, go to spa club and you will have crushes.

grass always looks greener on the other side. something you dont own always better than what you currently own.
