Bottom line isthat really,really sucks!! You did the right thing,as hard as it was to do,so you deserve much credit for that!
As far as that turn the other cheek crap though,I DON'T THINK SO!!!!!! That SOB would rue the day that he did that to me! The key though is that you can't care if he knows that you got him! This is where most guy's can't get it done,they are so intent on revenge and their ego's need the SOB to know that they got him back that they can't get done what they need to.
If you need idea's PM me,there are plenty of legal ways you can exact revenge.In addition to gut piles near his property line and the late night predator hunting.This guy wouldn't know if he was coming or going by the time I was done with himand he would never know that I was involved.
