insomnia & hallucinations

My boyfriend hasn’t slept at night for over a week now. He will sleep during the early morning 6am - midday 1-2 pm, cause he works 2nd shift but all through out the night he talks to me as if i’m awake with him, he genuinely doesn’t think i’m asleep at all, then gets upset that i “ignore” him. He also thinks I stay up at night/all night “playing” with myself, but when I tell him he wakes me up, he says he doesn’t cause I was already awake. The past 2-3 nights he’s been talking to “someone” he thinks is in the house with us. I’m really not sure what to do because when i ask him about it later in the day he doesn’t remember any of it. But I’m so exhausted from being woken up all through out the night or just getting up at 3-4am just so he’ll stop then leaving for work at 6.
