Mozza: this was never about you. There is nothing more you could have done to change this. Sadly, this is who she is or had become, and she will never be happy with anyone in this selfish state. Maybe for moments, but not in a mature contented, meaningful, committed way. She has some demons within herself. Please don't blame yourself.
