Learn the 5 Language of Apology Part IV

Learn the fourth language: Genuinely repenting.
This says, “I’ll try not to do that again.”
When you speak this language, you decide to change your behavior so you won’t repeat the offense. Tell the person you’ve offended that you intend to change, develop a specific plan for doing so, and ask him or her to be patient with you while you go through the process of changing from destructive to healthy behavior.
Write down your plan for change so you can keep referring to it, and when you fail, get up and try again.
Show the offended person that you’re making a concerted effort to change, and ask him or her to support and encourage you to help the changes last.
