I agree with what others have posted.

You mention Drugs ??? It is LITERALLY impossible to find stability while street drugs, abusing prescription drugs or alcohol is going on.

As for her using the word “ suicide” sure some people toss that word around for effect or attention but I caution you if she’s using drugs , alcohol or can’t get them ..anything can happen. The idea of ignoring chicken little and the sky is falling ...one day the sky is likely going to fall unless she gets herself healthy and that means medication, no street drugs or alcohol and working very hard with a Therapist to learn how to regulate anger.

What she is doing to you is mental Abuse and throwing a wine bottle hard enough to go through a wall ?? That physical abuse she could easily have hit you or your children with that bottle.

I advise you to start taking action to keep yourself and children safe. The lasting negative effect on children of fighting arguing parents lets them think that it’s okay to have a relationship just like good ole mom and dad.

Good luck
