I'm Not Sleeping As Well with My Boyfriend?

I normally take forever to fall asleep and sleep for a very long time. The first time I slept next to my boyfriend, though, I fell asleep instantly into a very deep sleep and woke up much sooner than I normally do but felt just as rested. My boyfriend and I don't get to spend the night with each other often, but I always slept that way when we did. Well, the past 3-4 times I have slept with him, I have been really uncomfortable and restless. I keep waking up in the middle of the night and still feel tired the next morning. Nothing about the bed has changed either. Could this be a subconscious sign that I'm not as connected to him anymore? I don't feel that way when we're together, but this makes me curious.

Suggestion:

No, it just means you're used to it.
