I liked that, Zen,
I really think that there an end to caring about an adult person who can potentially carry for themselves and try to live a good life.
Self-preservation is, in this matter, a common-sense deed, and I am glad you made this decision and stopped torturing yourself about the questions you could not solve.
When you feel all alone and unhappy, turn to you Inner Child and talk to Him.
You will see He can comfort you like nothing else!
