Why didn't your FML start with "My EX-boyfriend"? One night, while you're giving him head, he'll think your a demon sucking his soul out through his penis and then your head will slowly roll across the floor. Run for your life - - RIGHT NOW!

Op, maybe this is a mental health issue. Please be careful and don't just assume everything will be OK. Take it from someone who knows.

This sounds exactly like my ex.

Op, if you want to stay with your boyfriend, get him to talk to someone in the medical community. I mean, if he's wrong about the demons, he may need help. However, if he's right, a knife won't do jack (except maybe harm you in the process), and the talking with someone won't hurt. Might want to err on the side of caution with this one.....

Edit: research has since swayed my opinion. I am not saying that all documented possessions are the real deal but some are. Do some research and then get back to me. And try and keep an open mind. It's hard but try.

For your safety, you should leave him before he seriously hurts you.

He's either mentally I'll and potentially unstable or acting out a pathetic fantasy to get attention. Either way, disengage yourself from this loser (carefully) before you get hurt.

As long as you're not feasting on his soul, I see no problem for you.

How much soul does one person need? He's just being xenophobic, hating the poor soul sucking demons.

Oh, you could sleepover. Just keep one eye open.
