We all make mistakes that we wish we could resolve, prevent or erase, but sometimes, all we can do is push forward. When you're reminded of the problem, seeing each other in your case, it eats at you because you feel as if there is something you can do to repair it. "I'll be better this time" or "I've realized what I've done wrong." But as one saying goes, "the best apology is changed behavior. Keep in mind, changing your behavior isn't necessarily an apology to her, but an apology to yourself for recognizing what went wrong and bettering yourself for it. That is the message of regret. To make sure you don't repeat the mistakes and learn from them.

Due to this belief, you might feel entitled at a conversation, an explanation or another chance, but just because you're ready or feel remorse, the other person may no longer care or be to hurt to revisit such memories. "Life goes on, with or without you.

Sometimes, it's realizing that caring about someone means you want them to be happy, even if it's with someone else. Emotional pain is a sign. For what? That's for you to figure out, but hopefully, you don't let it make you angry, feel defeated or bring you down.

Learn from this and know the final straw wasn't just the only chance you had. Every day you have an opportunity to be better. Start today.
