Soulmates

SOULMATE: Any soul you were destined to meet in this lifetime.These are the people who will enter your lives.Some will stay, and some will leave. But for every soul that crosses your path, there is a lesson to be learned and a wisdom to be found. - Safinah
Sometimes I wonder, is there such thing as coincidence? Or may be everything was destined way back from lauh mahfuz?
Have you ever met someone for the first time and become "best friends forever" the next day? As if you knew the person for ages?

Have you ever saw someone but as if you knew that person but you couldn't make yourself to ask because you were too afraid it might not be the person you thought it would be? I know I did and it just happen to me yesterday.

I keep on wondering, is it worth it to do this seriously? I don't know and I put all this in the hands of Allah.
