A friend who forgave you when they didn’t have to gave you a second shot you couldn’t have earned. Don’t waste it.

Forgiveness is not a reward for improvement, which is what makes it strange. You did the thing, there was no way to undo it, and somebody decided the friendship was worth more than their right to stay angry. That is a gift in the strict sense: unearned, not owed, and freely withdrawable. Treating it as a reset you deserved is how people lose it twice.

Do not spend the next while apologizing again. Change the specific thing instead, and let them see the change rather than hear about it. If there is still something you never actually said out loud, say it plainly once and then let it rest.
