I have a friend, who's been married for 30+ years, that has a wonderful, close, loving relationship with her husband. And for reasons, similar to yours, they do sleep in separate beds.
I cannot think of a couple that is as much friends as they are lovers. Things like needing different types of beds, hogging the bed, hot flashes, snoring, sleeping patterns, etc.
I see it like this, instead of growing resentful with one another, over the little things like 'sleep wars', which some people may be compatible in every other way, why let something like this, build up and damage the relationship? Makes, for when one desires to share that bed for an evening here and there, all that more special, if you ask me!!
Hold your head up, if it works, and keeps your love alive, then by all means!!
