I guess I don't see the point in saying something outright to Steve. I got the impression Kelly's already told him this stuff isn't welcome, so what more is there to discuss? (Ha - and if you haven't, Kelly, what's wrong with you?!)

That's why I said cut off contact with him and quit responding to his emails -- if you've made it clear you're uncomfortable with the way he's talking to you, end the relationship. Just like any other type of relationship... if you had a friend who kept bringing up something that upset you, and wouldn't stop even when you'd asked them to, you'd limit your exposure, right? And this guy is just a friend of your boyfriend's. You don't owe him anything except to be polite -- certainly you're not expected to continue to field his inappropriate emails.

My point is, I don't think that's passive agressive at all -- it's the email equivilent of changing bar stools when the disgusting sex-starved drunken middle aged guy next to you won't quit whispering dirty words in your ear. Why allow someone else to make you uncomfortable?
