DH has announced he is going to be working from home permanently from July. He did briefly discuss it with me in advance, but it was more a case of telling me, as he's decided he can't afford the office he had in the next town anymore.
He used to work from home about five years ago and it almost broke our marriage, which is why he moved out to a small office.
So I'm dreading it all happening again 
. I'm wondering if I can set some "ground rules" to try to prevent the downward spiral again?
I also work part-time at home (copywriting/PR etc) and am also studying for another qualification.
Basically all the things he did last time which caused problems:
- Noise. Likes to have music on throughout the house and when he's working. Also whistles. Wanders around having phone conversations on his mobile. I need peace and quiet to concentrate and work.
- Comes to find me and ask questions/advice about things the minute he thinks about things. Last time I felt as if I had become his coworker/pa.
- Comes and stands in my office while waiting for printing and looks over my shoulder at what I'm doing/ comments
- waits for me to make coffee/ lunch and gets offended if I don't offer/ make him one/ a sandwich
OR uses up food I've bought for kids lunches/ weekend etc
On the occasions I am going out meeting friends/ going to a gym class he quizzes me and makes snarky comments about "how nice" it must be to be able to do that in the middle of the day 
.
