Thanks everyone. It does suck, and it was unexpected. I appreciate the kind words

I'm not sure how much he's even playing the game, to be honest. He seemed mostly to play it when he was at my place and when he's at his place he was playing other things so maybe I won't see him. I don't really mind if I bump into him in a duty because half the time I don't read names anyway. I just didn't really want to be wandering around in Ul'dah or whatever and see him. I don't think he'd cause any trouble since he's the one who wanted to break up.

But yes, this seems poorly implemented. You should be able to de-render someone or make them invisible somehow along with being unable to see them or be matched with them in a duty. It's a shame.
