I would think while your change has been positive and you consider the prior an asshole, they're still inseparable. But so are light and dark. Warm and hot. Yin Yang. To thy own self be true. You wouldn't be here without the prior... There's nothing wrong with who you were, necessarily. You've nevertheless changed. It's like the ship of Theseus. Replace enough boards and when exactly does a ship become a 'new' one? It's subjective. Yet the spirit carries on.

It's so great you've grown, changed, found a new you. Perhaps the old ship has sailed. Be the new you. Or simply just be you, and be here now.
