I have lived this and I will never waste time like that again. Time you can never get back. And you can feel so alone even when you are with someone. I would rather be alone then lonely with someone else. You should never feel that way in a good healthy relationship.
When that inner voice speaks to me next time screaming there is something going on... I'm gone. I've reached the point I'm my life that I'd rather be alone than share my spouse (emotionally or otherwise).
