i feel your pain, i think DP and i spend about an hour in bed together, i go to bed first, then he comes to bed later, then within an hour of him falling asleep i am awake and can't get back to sleep as he is snoring, or quite often just audibly breathing, but its enough to keep me awake, so i wander into the spare room and fall asleep in there.... its not very ideal for a relationship but neither is lack of sleep, so for me i put sleep first... i recently googled the subject and found a staggering number of couples sleep separately due to different sleep habits (snoring etc). made me feel less bad about it.
