marriage.....I convinced her to stay.
For any one reading this: live and learn. You can never, ever force emotional feelings out of no one.
Love is an easy, freely flowing positive energy. If it flows on the upstream then is not meant to be. All it does is to create forced interactions that in the long run it cannot be sustained.
More hurts and waste of time in your life is always the outcome.
I'm extremely realistic in this matter. If I was ever just insinuated, or told upfront that it wouldn't work, I always immediately turned around and say goodbye. I never, ever would ask to be wanted, because somehow I always understood that you cannot force love or a relationship. So OP eventually got what ultimately was the inevitable outcome.
