Honestly? I got a life. Of my own. I went out to meet new people, I hang out with friends, I spend better time with my kids, and so on.
I proved to myself that I can still be successful and happy without my wife in my life. Now I know I don't NEED her anymore. Sure, I want her to come back. But I don't need it anymore like I thought I would.
Once you achieve that, what's left to be afraid of? The worst has already happened.
