In most cases, you probably don't, but I'm not the one to answer that. Hell, I have to ask that question every time we move or my in-laws come for a month long visit. Major changes always put stress on a marriage, moving, kids, new roommates, relatives visiting, etc.
PS. I'm currently working on a struggling marriage. While we are in a much better place than we were 3 years ago, we are NOT strong enough for poly or anything else right now. So I do relate to the not wanting to be married anymore.
