Me! Though mine was for different reasons (DH got Covid in December, went from bad to worse to nearly dying, was in ICU in the New Year, came home mid-Jan and was just so damn ill, he should have remained in hospital... anyway, I digress!).
I developed this total and utter aversion to sleeping with DH after he'd been so ill. Our bedroom had become a sick room when he had Covid. When he was in hospital, I couldn't cope with the idea of being in that room where he'd gone so bloody downhill before my eyes.
Our bedrooms can become real trauma boxes! Illness, relationship problems, miscarriages, newborns, getting up and down all night with our non-sleepers for children, snoring- bloody snoring partners (couldn't sleep last night for all the snoring) can make us want to flee the bedroom! Sometimes you just need your space! I often retreat to one of the kids' bunks for a long 8 hours of Zen! No snoring, no dealing with DH getting up and down for the toilet (which is like a Barnum and Bailey's elephant parade going down the corridor).
I have returned to the bedroom and it's been absolutely fine on the one hand, though I am struggling with insomnia, I find. My loosey-goosey theory is that when we have babies and when we're in menopause , women just need calm, Zen, a full bloody night's sleep, and space. Our bodies are so fecking under attack by our hormones, whether the oestrogen tide is high or low, it totally rules us- among other hormones (and when we're raising little ones, we've got them crying from another room or even the same one! This just adds to the exhaustion).
My best solution of late is to sleep with DH (which I really do enjoy. Pain in the neck that he is, he's a great cuddler and a lovely guy) but always know where the exit sign is. When the snoring gets too much, I sneak off to my Zen bunk in the kids' room next door (it's an amazingly calm room- it's got beautiful energy, if you're into that sort of thing). Always have an escape hatch! Unfortunately, when the kids are small and sleeping is unsettled, it's just hard to get a restful night, OP. But don't box yourself into thinking 'I must be a good little wifey and sleep all night in the marital bed.' Bollox to that. Years ago, DH and I made a pact when the kids were small: Sleep. Sleep when and where you can. Sleep is everything. Sleep makes people get along better and live more harmoniously in a household. So go ahead and learn to sleep again with your DH, but have a little safe haven that's yours- even if it's the sofa once in a while. It's ok to want a bit of sleep space from time to time.
