Make a very clear statement of regret by specifically stating that you are sorry for having messed something up. It is important that you offer both a statement of remorse that lets your boyfriend know that you are sorry and an acknowledgement of what you have done. Failing to explain what you are sorry for can make your apology seem flippant or insincere, while saying only that you are sorry and not explaining the circumstances of your remorse can weaken the apology.

Ask your boyfriend to forgive you for your mistake. It is important that, while apologizing and asking for forgiveness, you avoid offering explanations that could be perceived as excuses. It is okay to offer some context or explanation, but focus more on your own regret and remorse. Asking your boyfriend to forgive you is a way of acknowledging that you have done wrong by him and that you value his love and affection and would like to set the relationship back on course.

Attempt to understand how your actions have made your boyfriend feel. It can be hard to imagine the feelings of others, but by empathizing with your boyfriend, you will be able to offer a more effective and heartfelt apology. The most successful apologies are tailored to the recipient and take into consideration the recipient's feelings and personality.

Offer to make amends by doing something to fix the situation. Although you cannot undo your actions, you may be able to rectify the consequences of your actions. The best apologies include a form of reconciliation that is specifically tied to the transgression. For example, if you scratched your boyfriend's car, offer to have the scratch repaired and the car returned to its prior state.
