My boyfriend held me all of the night while sleeping?

Before going to sleep, he positioned my arm across his chest, and held it there for hours. I got up in the middle of the night to go to the bathroom, and he called my name and said "What are you doing, come back here". When I did he kind of spooned me and held his arm over me for the rest of the night. We did not have sex. What's the meaning of it?
