I use "forgive" in the loosest sense of the word. If there was any "forgiveness" required, that would imply I harboured some sort of resentment towards them. I don't. That's not to say I wish them success in the future either. My stance is neutral as I'm past caring about what happened anymore and am looking at the bigger picture now. But yes, anyone who still "hates" them is completely within their right to do so. I totally get it.
