“I have been in a 5-year very toxic relationship with a married man. Every time I have tried to end it he goes to the extreme to make sure I don’t. He has told friends and customers about his affair with me and that he is in love with me. I have even considered moving out of town to get away from him. He is very controlling and has even threatened to kill himself if I leave him. Please help.”
Every threat of suicide must be taken very seriously. As the “other woman,” even if you were a mental health professional specializing in suicide prevention, you would be unqualified to sustain his life. Get out of the man’s way so he can get the help he needs!
He doesn’t love you. Love doesn’t threaten, control, or manipulate.
I trust you see you are “killing yourself” by staying. I’d suggest you move, that you do cut all ties, and that you do find your freedom at all cost. You cannot be a lifeline for any man, let alone one who demonstrates no respect for his family or for you.
Suicide, by very definition, is self-inflicted, and therefore his killing himself, which would indeed be very sad, would not be your responsibility, or your fault.
