How to do it?

Rey

I really need to get away from this guy but every time I try to break up with him he says he’s going to kill him self.

He has been in a psych ward before for attempting suicide and he has access to a lot of drugs one can overdose on. I tell you this so no one tells me he won’t really do it.

He also has Aspergers, a form of autism.

How do I break up with him without him killing himself?
