Girls what's your opinion ?

I am currently away from my boyfriend right now, we are both in college and we live about 3 hours from eachother because we are both home and on winter break. He told me to call or text him if I ever have trouble sleeping considering I'm used to sleeping with him now, somehow we both sleep either in my or his twin bed at college. I feel guilty for wanted to wake him up and don't want to. I have been told it is selfish to wake him up because it is not his fault for me not being able to sleep, but he is the one that told me to text or call him if I cant (I havent yet). He wants to always try to help keep sleep and he does when I'm with him and cant sleep he strokes my hair and pulls me in close and hugs me.
