How many of you have had an SO threaten suicide when trying to leave a relationship?

I was reading this article and was surprised how they connected suicidal threats to a murder threat as well. Has anyone had experiences with this or with suicidal threats in general?

I definitely have.

I was went on a few dates with a dude who clearly had anger issue and admitted to history of violence, so I left asap, but he threatened suicide right away. I definitely remember having felt instinctively I shouldn't breakup in person, and he had even taken some stuff out of my bag when I had been there last and said I had "left" it there and needed to come back and get it. I didn't feel safe going back and neither did my family so I just left it. I was afraid he was gonna come murder me for soo long.

But reading this article I think maybe that fear was more justified than I had thought.

I had read the books "Why does he do that" and "the gift of fear" and my knowledge from both helped me get out of the situation a lot. Been few years now and no murder.
