Hopefully you will keep what you know about your teacher to yourself.
My hopes are that you wont blackmail any person. Thats what cops do to those they catch. Tell and we can help you. Dont become that which you despise. It seems as though you and the teacher now have something in common. Why ruin it or jeopardize it? Do the right thing and respect your teachers private life.
