who wrong?

Somebody please explain to me why, why I can't pick on who I fall in love? If I can maybe I will never choose him. I will never on this situation. And God, tell me what am I supposed to do? If I'm wrong, I mean not me, but my feeling. If my feeling wrong, why are you not take this feeling away? Why? I can't understand, how differences between us can make us always together. God, if wrong, I just want to know the answer why me? Why him? And why this feeling?
