Weird Boyfriend!!

So last night when my boyfriend and I where asleep I woke up to him pulling my hair which was in a bun! I look at him and said stop and he was asleep so I was trying to go back to sleep and moments later he did it again and I asked why is he doing that and he said he didn't and fell right back to sleep. He also sleep talks a lot and it kinda freaks me out lol. This is something he never really done until further alone in my pregnancy. I've read if your partner sleep talks he's nervous about baby's arrival 😆😂
