LOL! @ Sandy & Janet.
My hubby used to work 2P - 12MN, 4 days a week. Then he would often go fishing or hunting on those 3 days off. We loved being together, but I loved that he could go off with his friends and do his hunting/fishing thing.
Then...... he got sick and now he is home 24/7

The first couple of years he was so sick, I didn't notice. Then he started to feel better and it started being hard NEVER being alone in my home anymore. I was so used to being alone over half the time. But then he felt well enough to go off for 2-3 days with his best friend and I enjoyed the break. Then his best friend died

And since then, he has pretty much been home - if he goes somewhere, I go with him because his health is in some decline.
We finally settled in to being comfortable with each other all the time. I have my office that I escape to and he watches TV or reads in the den. We are actually only about 10 feet apart though. We talk a lot every evening, and sometimes I would rather just be quiet after a hectic day at work - but I know that he needs to interact with me as it is boring at home all day with only the dogs to talk to
The point is that you can/will adapt to whatever life throws at you. It will take some time, but it will be OK! I know that you know that - so it's all good!
