I think DH is making this into something it's not to be honest, but it upsets him quite a lot.
Two or three times a week - sometimes more, sometimes less, depending on how tired or busy I am I sleep in the spare room. I just see it as a way to get a decent night's sleep, he seems to take it as some sort of rejection
I am a terrible sleeper, I take ages to actually fall asleep, then once I am asleep, a sparrow farting in the next street is enough to wake me, then I take ages to fall asleep again, sometimes he only has to touch me in his sleep to wake me up
DH fidgets and twitches, and whilst he's not an express-train type snorer, he breathes quite heavily which disturbs me, if I go to bed early and fall asleep before he comes up he always wakes me up (not deliberately) so I beat a retreat to the spare room for some peace - it also means that when I'm struggling to sleep, I can put the light on and read without disturbing him, instead of tossing and turning in the dark - win-win for both of us I would have thought
Sometimes I'll start off the night in our bed, then de-camp, sometimes I'll just say 'look, I'm knackered, I'm going to bed early and will sleep in the spare room'
I'm tired and irritable and get niggly with him as I resent him for disturbing me, albeit unintentionally, while he's getting his 8 hours uninterrupted beauty sleep
He seems to take it as some sort of rejection, when really, I'm just really, really tired/have a busy day or early start the following day, and I just see it as the best way for everyone to get some sleep
