Stopped by for one of my very rare pop-bys, and here you are. Usually there's no one I know on the first page.
FWIW, ITA w/ shewholurks' two posts above. #1, forget stats. Every sitch is different, you can never find enough "apples to apples" to get anything meaningful out of them. #2 live your own life and let whatever happens happen.
Now for a brief lecture. You are not a failure. You did not make him leave. It was his decision. If he hadn't left that day, it would've been another and for some other reason, trust me. The fact that you've convinced yourself of this fiction that your actions resulted in his taking off is just keeping you afraid of your own shadow. You gotta shed that and LIVE. I'm not talking about getting a new man, just LIVING for Once. As others have said, what he does next will be his decision too. It may have nothing to do w/ what you do.
Who am I to crush hope. So I won't. Me, I think I forgot what hope is. H moved a jillion miles away, got the D and M his gf from high school. I don't see or hear from him but I hear enough to know his life is very happy. How can I wish that to end? How can I be sorry that this person I care so much about is happy? Maybe being M to H forever was not my destiny. Maybe I was just a chapter in his book. And now I'm back to writing my own.
What's your destiny? Putting aside OM (I never wanted that either), if H were dead, what would you do? Think about that. Live that.
