Is it normal to be left in the dark?

My boyfriends a great guy but I always feel like I'm walking on eggshells with him.
Problem is, I can't watch, eat, wear, or even think like his past girlfriends.
When he notices I resemble them at all (with my actions or hobbies) he leaves me in the dark, literally! He leave's the room and turns off the lights as if I'm not in the room.
When I meet him in the opposite room, I'll ask what happened, and he says "I was uncomfortable"
So because you're uncomfortable, I'm left in the dark like I don't exist?
If I mention them, we get into an argument.
If I watch a show one of them liked, we get into an argument.
If I wear anything that reminds him of them, we get into an argument.
But he can talk to everyone else about them, talk to their family members about them, and be completely fine with the conversation - and also completely secretive.
It's almost like he's obsessed (I mentioned this to him and he responded "I'm traumatized")
I'm having second thoughts as to why I'm in this thing in the first place, maybe he needs to do some self healing and I need to move on?
