How do you cope?

We are thinking about hubby going away for work, week on, week off.

I am extremely independent, not concerned about when he would be away, I know I'd be fine...

I'm worried about him being home for so much time at once! I'm worried about having a good routine when he's away, only to have him come home and have to change everything to suit him! I'm worried about how I'll feel about him having so much time at home while I'm working (only part time, but you get my drift). I just don't know how I'll cope flipping from one extreme (never home) to the next (ALWAYS home!!!)

Any experiences?
