I'm very sorry what/how you had through. I know that feeling. You are not only one and first person who are very disappointed... We (each person) have the same as you but accept and move on then we know for the sure that we won't involve with this ever again.
I do not wish that you shut us for the good. You know that there're bad or good people around... If you know there're bad people then you will know that you won't involve with them ever again and find your way to enjoy yourself and meet new people.
I find sad that you leave AD but I respect your wish for this and remember that we will be there for you when you come back...
