Sleep talking

My boyfriend and I live together and honestly I enjoy every second of it. Tonight we went to bed and he passed out right away. I was having some trouble falling asleep so I sat on my phone a little and then got up to use the bathroom. When I got back in the bed I looked over to check on him and when I looked over he was looking at me with these wide eyes. I was startled because I was expecting him to still be asleep. I told him he scared me and then his eyes started to close and he started rapping. Only a few seconds later the words faded and he fell back asleep. I just really enjoy having him by my side every night and day. I appreciate him and all the little things so much.
