Sounds like a good time to transition him to his OWN bed. And have Daddy help.
Put up a gate on his room and put a mattress on the floor. That's his big boy bed! Have dad put him there. Lots of hugs and love. Books to read. Same stuffed animals he's used to, same pillow, blankets.
Let him be upset. He'll be okay. Let dad go in and comfort him. Don't give in and don't give up. He will fall asleep and you'll be there in the morning to greet him with hugs and praise and smiles. "You slept in your big boy bed? WOW! That's Awesome! Mommy is soooooo proud!"
It will likely get worse before it gets better. Stick with it. I bet it will take maybe 3 days before he isn't demanding you anymore. You say goodnight from the living room, dad puts him to bed, and he STAYS there. Don't go looking in his room and getting him riled up. Let dad take this on. It will be okay.
Best of luck!
