Hello Rod, thank you for replying.
It was a 14-year marriage, ended in divorce about 8 years ago, property settlement all done and dusted.
We lived apart for most of those 8 years, but due to ice addiction, my ex became schizophrenic and homeless.
We have seven children, mostly grown up and gone, but two teenagers love with me.
When my ex reached the point of living in the back of her car, I invited her to come live with us until she found her feet. She has been here now for about 6 months.
Now I'm regretting asking her, but whenever I try to ask her to behave better, she flares up and becomes violent.
I'm not sure what to do.
