To be fair to Candace, she didn’t suggest that Liz broke up with Anthony, Liz has been whining about being bored with him but doing nothing about it. Maybe she just thought: for heaven’s sake, shut up! And found a drastic way to get her to act. Also, it is making Liz realise a bit more clearly how she feels about Anthony. (However, like you, I know how this all pans out.)
Not vegan though
