Is my boyfriend a crazy psychopath?

My boyfriend keeps making jokes saying if I try leaving him he would lock me up and tie me up to his bed he also said if I try to breaking up with him he would kill me because if he can’t have me “ no one can” he told me he was joking but this is the 4th time he made a “joke” about this. I’m starting to think he isn’t, even as a fantasy it is disturbing is it time to let him go?
