soul mate??

How can you know if that someone is your soul mate?

Is it by looking into his eyes that make your heart skip a beat?

Is it the way he hold you that give the warm and safeties feeling in the world?

Or it is on his smile that give you a million butterfly in your stomach?

But what if someone own him,
someone holding his damn hand,
someone making him smile
Or he is in love with someone else,

is it mean your become soulless?
become empty?
or maybe just accept the fact that you two are just connected by soul but not by heart.
