When my ex started touring we made an agreement to talk everyday and to share our day to day activities. Being on a tour bus for several weeks is like going to camp in the respect that you pick up new mannerisms, tastes, and even politics. You bond with your coworkers deeper than most people because you are working, eating, breathing with them 24/7.

I didn't want him to come home a stranger. At first it worked well but as he toured more he didn't want to talk about work. He didn't want to share and when I shared what I was doing, he called it small town and mundane. I got to the point where I was trying to think of clever and interesting things to say to hold my own husband's interest.

He stopped wanting to be my witness and figured that the rest of the crew was witness enough for him. They validated him. Of course, this started about the time of the affair. He grew more and more distant with me.

I miss having someone around. I talk to the dog and yet things really haven't changed much since H became X except for the lack of daily phone calls. It is unnerving to think if I fell changing a light bulb, it would take some time before anyone figured it out.

I think that quote is right on. It really knocks the wind out of you when your spouse leaves because there is no one to empathize and laugh with you. That sucks.
Of course, in my case and many others, my x checked out months before he told me, because he toured though, it was hard figure out. Heck, he even took a vacation with his gf and I had no idea. Thought he was out with a band. Good times.
