A solid compromise that sometimes works when getting up and leaving just seems inhuman. One could push two beds together. This makes a ton of difference because, although it doesn't cure the noise factor, it does ameliorate the tossing and turning factor. That is, you're sleeping, or laying awake more likely, next to your partner, but when you get up or move around, they don't feel it because you're on a different set of springs. This way, if the non-insomniac is not a snorer, the two can "virtually" bed together, (with twin beds even put one king size cover sheet and the thing even passes as one bed.) Other times I've slept on a therma rest pad right next to the beloved's bed and manage to log some zees in relative peace and with minimal self-consciousness. Plus, the normie person has the security of knowing you're just a couple of feet away and can be called for some cuddling or whatever when needed.
