Dating a roommate or?

So Saturday my room mates and I got totally shit faced drunk. My one room mate and I are the same person when drunk. So him and I were total shit heads the whole night. We got home and everyone was going to bed and someone was sleeping in the couch, so my room mate and I watched a movie in his room. He passed out within the first 20 minuets and I fell asleep not long after. I remember waking up at 4 am to him covering me up and then pulling me in and holding me. We spent the rest of the night sleeping like that. It was so nice and idk I just really enjoyed it. Anyways I don’t think he remembers and or cares and I don’t know what to do. Should I ask him about it or just leave it?
