Who left who? For those of us who had a SO that was religious, was it you or them that left?
Most of my partners have been agnostic or atheists. Technically, my most recent ex was religious and she left, though religion had nothing to do with why we broke up
I left her because regardless of how much we both loved each other I knew she was waiting for the Christian man I was when we first met. I knew I could never be that guy again
