I've had my days to myself too long to be followed around or asked why, what, when, and how all day.
I told him one day he or I may be dependent on one another 24/7 but it's not that day yet and I don't need a companion to go grocery shopping. The last time he went with me to shop for paint and house stuff, we took separate cars. I can't deal with the I'm ready to go look. That gets me really angry. He should have stayed home.
