Hi guys , Related to one of other posts , a former friend of mine kept convincing me for close to a year that my wife is dating someone else. I initially ignored him but later that started impacting me as I started suspecting my wife. After a year, I came to know that friend was spying on wife's phone as well. I broke up with him and banned him coming to my family. He still to tries to interfere in our family life on and off. I was wondering if all this stands a chance for filing in a defamation case against him? Also, I am in NSW at the moment. This incident happened back in VIC.
