I call every time she does it, and every time it costs her $500 or more. I also call when she threatens to commit suicide. Granted, it's been almost a year since she has done either, but she also knows it's my policy to call 911 always.
Coincidence? Maybe. But since I instituted this policy (and her brief stay in jail and misdemeanor conviction for child abandonment), she has only relapsed once and it was low-level (still conscious, took accountability and didn't say and do crazy **** for the most part).
This is another good reason to divorce and separate finances. Her bills are hers, not mine. Her last incident, including court costs, hit her to the tune of over $3,000.
Take what you want and leave the rest,
