My dad use to say, I would much rather a good guard dog than a gun. With a gun you could stay awake in wait for what’s to come but eventually you’ll grow weary and sleep will become your master.
However a dog never sleeps!
So too with “Intent”!
Stop checking, spying and harassing yourself into the futility of controlling another. For if it is their “Intent” to do what you would otherwise wish not, they will do exactly that which is their “Intent.”
They will simply await your falling asleep.
Trust is your only weapon and that is as good as it needs to be, all other things are your insecurities.
