Why is letting go so hard?
Because we aren't holding on for their sake, we are holding on for OUR sake. We THINK we are abandoning them, we FEEL we are abandoning ourselves.
The solution is to do it anyway, to let go, and then take care of ourselves without putting them in the middle.
It's like we need money, so we given them money, to give to us, so we don't feel poor. We are afraid if we leave, they won't give us money any more and we will be poorer than we are now.
What happens is, we leave and after a bit of pining for the money they don't and have never given us, we realize, hey! look at all this money I have, now that I'm not giving it to him to give to me.
