He’s unlikely to wake up one day thinking, “I hurt her, I was wrong, I owe her an apology.” Men like this rarely get there. That would require real self-inspection, and he’s spent a lifetime avoiding that.

His regret won’t look like remorse.
It’ll look like irritation, defensiveness, maybe quiet anxiety when her name crosses his mind.

If he ever does regret it, deeply and genuinely, the most ethical outcome for him is to live with that regret privately.

Not to unload it onto her.

But to let her know one day, that he is living with it.

Then, it will be up to her, to open the door, or keep it forever closed.

Because he punished her for her very instinctive characteristics: feeling so alive.

She entered a system with energy, and someone unstable tried to feed on it instead of protecting it.
