how would you tell your former love that you're over her?
I'd try to avoid having this conversation as much as I can because: 1) if it matters to her, there's really no easy way to say it (so the answer would be I'd just go on and say it, if she asks), and 2) if it doesn't matter to her, then what's the point of saying it? Vindication? Catharsis? It isn't worth it. If you've moved on then enjoy that.
