You have every right to establish boundaries about what should/should not be discussed with the kids. I agree with you that his comment was completely inappropriate to your D. Whether or not he suspects you of an A, he does not need to be discussing this with the kids.
I also suspect, he is afraid that you are having an A...because you are doing IMO what you should be...getting a life. From what you've written he's been snooping & checking up on you just as NOPkins has so rightly advised some of this BB members to do. He may say mean and anflammitory things to you, all in the attempts to control you...but I believe he is afraid you will walk out that door, you will have enough of his behavior one of these days and tell him exactly where he can stick that computer of his.
You have a right to your friends and to your life and to happiness...you aren't doing anything wrong, so let him snoop. He's not going to be catching you doing anything you shouldn't be...now is he? I say let him sweat a bit.
