Can The Saying "If tu amor Something Let It Go, If It Returns Its Yours." Work for people in your family?

Don't Take it the wrong way, i'm not in amor with any family member but someone in the family i really amor is living in new york.

She's the only one in the family who treated me like a grown up when i was the youngest in the faimly, shes treated me like a sister, when my own sisters didn't.

But now i'm miles away from her. if i was to drive over to her it take weeks, days por plane.

And i just want to know if the saying will work for family members.

even though shes only 16 living with her mother and her new born baby.....

but i just want to knew, if she ever moves back, will she stay? i know no one can tell the future, but....can tu tell me the odds?
