Boyfriend hallucinating …

My boyfriend has stayed up for 4 whole days playing nothing but video games. Fast forward to today, I woke up and he was completely angry, I didn’t have a clue why. He said “your so disrespectful you let him touch my baby” mind you im 26 weeks pregnant. I didn’t have a clue what he was talking about. He then said he saw me leave my house to go be with another guy but I was sleeping the whole time, I explained to him it didn’t happened and he lost it completely saying “so who was in your body your telling me I’m crazy” he thought I was cheating on him with my first kids father so I proved to him by showing him messages that never had happened. I tried to get him to sleep, however he slept for an hour the most. In his sleep he would laugh, and jump and I would ask if he’s okay and he would say completely different things than what I was asking. I’m so worried 😩
