I'm glad you stood up for yourself, even though it probably makes you sad and is hard.
The next time he says something about "the website," how about saying to him "I needed some support from other people who are going thru what I am," and leaving it at that? Although I wouldn't necessarily shy AWAY from using the "a-word" with him when appropriate, there's no need to beat him over the head with it, either.
Based on his past reactions, he's going to be pouty with you. Which REALLY ain't very attractive, now, is it.
