Letting go really does work

I was looking for answers on breaking the cycle of old emotions
(fear of rejection hurt ect).
Letting go, simple yet so effective. I experienced this last week.
My results where instant. As soon as i fully let go (i felt it leave my body through goose bumps and then felt content) the person i was involved with
(and had not heard from in some time) contacted me...instantly, it was a little frustrating actually. Perhaps a coincidence.
Just as i felt i was over him. Whats with that?
Did i take the 'pressure' off him?

At least I know it works now and can use it on the bigger issue that put me in this situation in the first place.
