I think there may be a few variables here including your type of mattress. When we were younger, we had an old-style mattress and when I got into bed it would affect my wife's movement and we would inevitably roll together. Now we have a memory foam mattress and my movement's do not affect her.
I have always known that I do not sleep well but my fitbit flex gives me a reading on how poorly I have slept. Considering that I work shifts and my data when I am alone in bed are very similar to when my wife is with me indicates that her movements are not causing extra "restless" to be recorded.
