Heartbreaks hurt but they also teach us a great deal about relationships. When your pain finally fades away and your wounded parts start recovering, you will realise that you no longer fall for a person's words but always make sure that their actions match up to what they're saying. You will notice the red flags in people much sooner, and leave immediately instead of giving them more chances to treat you badly. You won't waste your energy on anyone who isn't willing to give you their whole heart and commit to you properly, and best of all, you won't blame yourself when someone walks out of your life without warning. You will understand your worth more clearly by then, and so you won't diminish your own value because someone else couldn't recognize it.
