The one?

A friend of my gf's ask her how do I know if she is the one? And my gf asked me that, well I could not answer her at that moment, coz I know the feeling but cant explain it in words. So I thought about it. Hmm to me. She is the one when you like her, but she leaves you. And you feel happy for her that she found some one, and you try to comfort yourself and tell yourself that if its meant to be its meant to be. And by some miraculous event, the two of you come intertwindled back into each others lifes. Only to be pushed away yet again, and the last time that she came back into my life, I truly felt that she was the one... In short, you will only know if she's the one if you let her go and she come back to you. Just like the song Heaven Knows. ¨ If you really love her, you've got to set her free. And if she returns in time, I'll know she's mine.¨
