With my ex-husband (my kids' father), he literally would wake me up yelling at me for breathing too loud. If I rolled over to a more comfortable position, he got angry if I accidentally bumped him. He also got angry at me if he bumped into me when *he* changed position, and when he was tired, it was always my fault because I kept him awake somehow or other. I learned to sleep on my side, on the very edge of the bed, barely breathing and most nights barely sleeping.
That's why I have trouble sleeping with someone touching me and used to have trouble falling asleep in the same bed with someone else. As I said, I've learned to do so with Hubby, but we have a queen size bed and I still tend to stay close to the edge on my side. And most of the time, I wake up if I change position so I can make sure I don't bump him.
Even with S2, who was the partner I mentioned in my previous post with whom I didn't have problems sleeping even if he was holding me, for a few months I tried to stay on my side on the very edge of the bed. He only had a full-size bed, so there wasn't really room to change position without bumping into him. I didn't want to piss him off. But because of my fibromyalgia, if I stay in one position all night, I wake up in a lot of pain, and sometimes the pain hits during the night and I can't get back to sleep.
One of the mornings when I woke up hurting so badly I could barely get out of bed, he asked me what had caused the pain, and I told him I hadn't changed position all night and why. That upset him; he told me that my being comfortable and not in pain was way more important than whether I bumped into him while changing position, and that he would probably sleep through it anyway. After that, I didn't have a problem with changing position either. I still usually woke up if I was changing position, but it was more to make sure I didn't fall out of bed than to avoid bumping him. (I did fall out of bed twice... a full size bed is not ideal for two adults.)
I left my ex-husband in December 2006. The first night I spent with S2 was November 1 of last year, nearly eight years later. Until the conversation with S2, I hadn't realized how badly my ex's crap still affected me. I'd known my ex's behavior was behind my sleeping-with-others difficulty, but I hadn't realized how deep it went until I realized in the course of that conversation that I was actually afraid S2, one of the calmest, quietest, gentlest guys I've ever met, would be angry and possibly hurt me if I woke him up by changing position in bed.
