- Identify two reasons why you regret your actions or words.
Remember the emotions of the last time you were offended. This will help you feel more compassion for your partner.
Ask yourself: Why did I feel the need to act in a way that hurt or upset my significant other? Did I do it on purpose?

- Take responsibility for your hurtful words and actions.
Admit that you were wrong.
Say something like, "I take responsibility for my actions. I'm sorry they hurt you."
It can change your relationship.
"One person's response literally changes another person's brainwaves," write Drs Julie and John Gottman.

- Use the words "I'm sorry" and "I was wrong."
An apology is more likely to be accepted if you use these words.
Be specific about how you offended or embarrassed your significant other.

- Explain how you plan to right the wrong done (if possible).
For example: if you offended your mother-in-law, you can offer your apology to her over dinner.
Or write a note.

- Describe what you did or said without any excuses.
And accusations towards a partner or someone else.
Say "I", not "you".
For example, "I was yelling because I had a terrible day and needed to get back to work. I'm so sorry that I hurt you with my behavior."
And by no means: "You promised that we would have dinner today at six. You did not keep your promise, and I did not hold back."

- Apologize.
Make sure the environment is conducive to private conversation and there are no distractions (television, phones, children in the room, etc.)
Be specific about what you're apologizing for.

- Don't let your wounds poison your love for your partner.
Forget the doomed thoughts of how to keep your pride.
Briefly discuss what happened with your partner.
This will allow you to leave resentment behind and move on to a healthier relationship.
Always remember the "big picture".
