Here is how to apologize to your partner: say "I'm sorry" plainly, name exactly what you did, show you understand how it affected them, and say what you'll do differently. Keep any explanation short, drop the "but," and don't demand forgiveness. Then let your actions prove you meant it.
If you are still in the heat of a fight and need to cool down first, start with our guide on what to say after an argument. This page goes deeper on the apology itself: the part most people skip, examples for common situations, and what to do after you have said sorry.
Karina Schumann, a University of Pittsburgh psychologist who studies apologies, said on the American Psychological Association's Speaking of Psychology podcast that there is no perfect formula and sincerity matters most. Still, a few pieces show up again and again in research:
Clear words. Schumann calls "I'm sorry" or "I apologize" a strong signal that you are actually apologizing.
Ownership. Name what you did in specific words. Schumann says people who were hurt want to hear you accept at least some of the blame.
Impact. Show you understand how it affected them. More on this below, because it is the piece most apologies leave out.
Repair. Say what you will do differently, or ask what would help. UC Berkeley's Greater Good Science Center suggests asking the other person what would mean the most to them, rather than doing what mainly eases your own guilt.
An explanation is optional. Greater Good notes that a short explanation can show the harm wasn't intended, but long, excuse-like or blaming explanations tend to backfire. One sentence is usually plenty.
Utah State University Extension offers a simple version you can remember under stress: acknowledge their feelings, apologize for what you did, briefly explain, then apologize again. For example: "I can see you're upset. I'm so sorry I was late for dinner. I thought I could beat the traffic, and I was wrong. Again, I'm sorry."
Schumann says acknowledging the harm is underused: about 85 to 90 percent of the apologies she codes don't include it, even though people usually want to hear it. It sounds like this:
"I can see that made you feel like you didn't matter tonight."
"That must have been embarrassing in front of your sister."
"You were counting on me, and I left you to handle it alone."
If you honestly don't know why it hurt so much, ask before you apologize. Schumann suggests something like "Can you explain to me what you're feeling so that I can better understand?" Then listen without correcting the details.
Rewrite these until they sound like you. Your partner knows your voice.
You forgot something that mattered: "I forgot our anniversary dinner. I'm sorry. I know you planned it and were looking forward to it, and I made you feel like an afterthought. I've put next year's date in my calendar, and I'd like to plan a night out this week if you're up for it."
You said something hurtful in a fight: "I'm sorry I called you selfish. That was unfair and it wasn't true. You were trying to tell me you were tired, and I attacked you instead of listening."
You broke a promise: "I said I'd stop checking work email at dinner, and I didn't. I'm sorry. It tells you work comes first, and it doesn't. My phone is staying in the other room from now on."
It keeps happening: "I know I've apologized for this before, so words aren't enough. I'm sorry. Here is what I'm changing, and I'd like you to tell me if you see me slipping."
You both played a part: "I'm not going to keep score. My part was raising my voice and walking out, and I'm sorry for that."
That last one follows a Gottman Institute idea. The antidote to defensiveness is to accept responsibility, even if only for part of the conflict. You can own your share without pretending the whole thing was your fault.
Bigger breaches of trust. For something serious, such as infidelity, Schumann says an apology is only the start and has to be followed by actions that show a commitment to change. Greater Good gives counseling as one example of the behavior change that can rebuild trust. A licensed couples therapist can help you both through it.
"I'm sorry if you were offended." Schumann calls the conditional "if" apology the worst case, because it puts the focus on their reaction instead of your action.
"I'm sorry that this hurt you." She says this also shifts blame, implying they are too sensitive.
"I'm sorry, but..." Everything after "but" becomes the excuse. Save context for later, if it is needed at all.
"Mistakes were made." Greater Good flags vague, passive wording like this because it doesn't say who did what.
"That's not like me." Greater Good notes lines like this can suggest you aren't taking full ownership.
Defending yourself. The Gottman Institute describes defensiveness as righteous indignation or innocent victimhood, and calls it a way of blaming your partner.
Beating yourself up. Greater Good warns that self-punishment may ease your guilt without helping the other person.
Expecting instant forgiveness. Schumann advises apologizing without making forgiveness a condition.
Don't rush it. Greater Good advises against apologizing at the very start, before the other person feels heard, and cites a study where later apologies were more effective. Let your partner say how they feel before you get to "I'm sorry."
Texting. Schumann says there is little research on apologizing by text, and sincerity matters most. If texting is how you two normally talk, a sincere text may work. A surprise text about something serious can look like avoidance, so use it to open the door, then talk in person.
Small repairs count. The Gottman Institute defines a repair attempt as any statement or action, silly or otherwise, that stops negativity from escalating. It notes that in Dr. Gottman's research, repair attempts that consistently fail are a sign of an unhappy future. A quick "Sorry, that came out harsh, let me try again" in the middle of a disagreement is a small apology that keeps things on track.
Follow through. The change you promised is what makes the apology believable.
Give it time. Utah State University Extension notes that forgiveness can take time. Schumann suggests that someone who isn't ready can say "I'm not quite ready yet. I need more time," which is kinder than silence.
Don't reopen the case. If they need to talk about it again, listen again.
When you're on the receiving end: Utah State's steps are listen, receive, believe and accept. Accepting doesn't mean the hurt disappears right away.
If you feel unsafe: this advice is for ordinary hurts between partners who feel safe with each other. If you ever feel afraid of your partner, put your safety first and contact local emergency services or a domestic violence hotline.
Apologize for your part only, specifically, without adding "but you also." The Gottman Institute suggests accepting responsibility even for part of the conflict. Their part is a separate conversation.
Sometimes. Schumann says sincerity matters more than the medium. For anything serious, follow up face to face.
Don't push. Say you understand they need time, keep your promise, and check in gently later. An apology is not a demand for forgiveness.
Lead with "I'm sorry I..." and stop there. If an explanation helps, keep it to one sentence and never use it to shift blame.
