Suing for Slander against bad neighbors?

It is hard to prove and in most cases doesn't solve the problem. I have been in your situation and I do feel for you. The only solution is the one you have done. Put your house on the market and get out. Its also what I had to do for the sake of my son who was around your son's age. I am so sorry this has happened to you but please know you are not the only one and you are not alone. The neighourhood will be all the poorer in your absence but you need to think of your family. By the way, what happened when we moved out was eventually another neighbour was picked on and had to move and on and on. Some people are very destructive and I have not explanation for them. Just get out of there as soon as you can.
