" If you love somebody,
set them free.
If they don't come back,
they weren't yours to begin with."
That's an old saying which attempted to make parting with a loved one easier. Or at least seem that way.
A nice thought in truth : That the bond between you and the other person is so strong it is able to endure beyond the boundaries ot distance and time.
A caution however is that, if you do decide to set someone you love free, make sure they know you're setting them free as opposed to discarding them like a worn piece of clothing.
Otherwise, you may just end up loosing your one true love in this world.
But really, can you will yourself to let go and break the shackles that bind you to one another? Are you brave enough to risk everything you both share? It's your precious moments, memories and bond.
It's really like opening the cage door of your favorite pet canary and praying that although it will fly out of the cage, it will return to you by evening. And if it doesn't, does that mean I got to the pet store and pick up a new pet?
