I have been retired for a little over three years, my wife is the CEO of her business and she works long hours. I planned when I retired to travel alone some and have been about half timing it. We miss each other when I'm gone but we talk at least once everyday and email/facebook often. When she retires at the end of this year I will probably stay home more but she will go more often. I will still spend some time on the road alone. While it may not be for everyone, it has worked for us.
