I very much worry over those who simply see a woman scorned in Jodi instead of the walking, talking epitome of abusive behaviors she actually is. (Please understand I am not trying to be belittling or dismissive either...this comes from a good place, I swear.)
When you can't, or won't, see abuse for what it is just because it doesn't look the way you'd presume it opens the doors that you, or those you love, may become victims of it yourself. Apart from his murder - no matter what your 'mate' does, stalking is never acceptable - it is a form of psychological torture. Violating boundaries and their privacy constantly isn't okay either. Destroying another person's property or warning folks off someone just because you're jealous shouldn't become alright because he did a,b,c first. It's wrong, period. And just those actions alone are very congruent with a batterer for a very sound reason - abuse is always all about control.
A relationship with a psychopath is something I truly wouldn't wish on my very worst enemy - much less the gentle, compassionate souls that often follow this forum.
