Scout, I've spent much time and many words worrying about the retaliation. I wish I could have the time and the worry back again. What I have learned is that when I show mine how to hurt me, he does it again and again. I would try not to let him know the things that really eat away at you. When you don't react as he hopes, the fun of doing them will cease and he will move on to something else. I've let mine continue to mess with logins to different sites and mention it to him every so often. I could care less. He's locked out of the ones I care about and he can keep thinking he is bothering me with the others. Stops him from doing the things I really care about (and keep very hidden from him).
