“...a suicide is on the suicidee.”
Except this one. She drove him to suicide with endless texts and insults and encouragement to kill himself.
She left an electronic trail that proved she was on him like a demon trying to seduce him into self-destruction, up to the final moment. He had backed out at the last minute and she jumped in and browbeat him into it. Her intent was murder.
“Her intent was murder” means nothing.
Block the text messages. Every phone lets you do that. Complain about harassment.
But if you commit suicide, it’s on you.
