Confuse Soulmate

What is Soulmate?
Many people think soulmate must be lover,
For me, i think can be different,
Soulmate can refer to BFF,

After few years apart,
Felt this soulmate seem far for me,
Or is me alone refer this as soulmate,
but vice versa for this person,

Think i shouldn't too care,
Of what the things did,
and fall on this person,
I'm CONFUSE
