When I get into the realms of "what if, maybe I/he will, perhaps I/he should, if I do/don't do", all I end up with is stress, bewilderment and indecision. I cannot predict what will happen, just have guesses and 90% of those guesses do not eventuate, but they worry the hell out of me for a while.
Detachment to me, is giving others their right to make choices and decisions for them, whether I like what they decide or not. I have the same right to choose otherwise for me, and act for my good.
I have enough worries relating to my life, as I wish to live it....without spending time worrying how others choose to live theirs.
If what they want impacts badly on me then I get out of their way, or keep contact to the minimum.
It is so much nicer and easier for all that way, and I need not be involved with anything or anyone who puts my peace of mind or health at risk anymore.
God bless
