With me it was accidental. I had suffered several large disappointments over a period of about 20 years including a divorce 12 years earlier.
I felt fine but after an MRI doctor told me I had 5 growths on the upper node of my liver. He suggested a biopsy to confirm cancer. I told him to forget it and I went home. I was as angry as much as I was afraid. At that moment I gave up my religion entirely. I continue to believe in God and I strive to be a decent person but no more formal religious doctrine for me.
Almost immediately I felt a great sense of relief. I no longer believe in Heaven or Hell and if I have cancer it will eventually become apparent and if there is pain involved there are plenty of things the doctor has that will remove that. I will just die and go to dust painlessly. That's all.
My vigor for pursuing the "right" women has improved dramatically. The only real problem I have is discovering that women over fifty no longer care much for sex and if they do it is begrudgingly. None of them really enjoy it. Age.
But the main consideration here is, is that even though I have several women that I might consider asking to move in with me but probably will not. Why? Because I know the minute I did everything would change for me. Right now (outside of that fantastic woman) life is very good for me. I am retired, own my own home, my income is good. I am totally independent, I have a life and I love myself.
I only need be reminded of a good friend of mine who at just 32 was a field grade military officer, bachelor, drove a beautiful Mercedes roadster. He fell in love with a woman and never truly enjoyed life again. He doesn't to this day as a result of being harnessed. He is now retired but his wife still works, runs the show and I mean she REALLY runs the show.
I love myself entirely too much to allow that to happen. Possibly a live-in lover-woman but marriage again? Never. I love myself too much.
