when i think of "soulmates," i always think of it in a romantic way, too...
but i guess a soulmate could be anyone who you're deeply "connected" with. it could be a lover, a best friend, or a stranger... any person who you feel connected with on a level that feels like an entirely different dimension
the first time you meet, you feel as if you know the person from another lifetime or something... and you have this strange magnetic pull
towards each other.
it's a pretty intense experience.
it's amazing though...
and soulmates are pretty rare... so if she was serious, then you should feel lucky to have met her.
and even if she was joking, i'm sure that she meant it in a good way.
