Struggling to Forgive: AITA for Holding onto Past Betrayal by Sister?

A 28-year-old woman refused to just “move on” after her sister broke a promise in the most personal way possible. It wasn’t a small secret or harmless gossip, it was OP’s relationship mess, the kind of thing you only share with the one person you trust to keep it quiet.

OP told her 24-year-old sister about problems with her then-boyfriend and begged her not to repeat it. A few weeks later, OP found out her sister told her friends, and somehow made the story worse, so OP looked bad in front of people who weren’t even part of the original problem.

Now the sister is apologizing nonstop and trying to prove she’s changed, but OP can’t unfeel that betrayal every time she sees her.

Original Post

I (28F) have been struggling with a dilemma involving my younger sister (24F) recently. About a year ago, I confided in her about a personal issue I was facing—my relationship problems with my then-boyfriend.

I explicitly asked her not to share this information with anyone, as it was a sensitive topic and I needed her support. However, a few weeks later, I found out that she had not only told her friends about my situation but also exaggerated details, making me look bad in front of others.

This breach of trust hurt me deeply, and I confronted her about it immediately. She apologized and said it was a mistake, but the damage was done.

Since then, our relationship has been strained, and I find it hard to confide in her or trust her with anything personal. Recently, she has been making efforts to mend our relationship, apologizing multiple times and trying to prove that she has changed.

She's been supportive and there for me in other aspects of my life, but I can't seem to let go of the hurt from the past. Every time I see her, I'm reminded of the betrayal and struggle to move past it.

I feel conflicted because I value family and forgiveness, but I also can't shake off the feeling of betrayal. AITA for not forgiving my sister for her past mistake, even though she's trying to make amends now?

The Weight of Betrayal

The original poster's struggle to forgive her sister is a reflection of how deeply betrayal can cut, especially within families. When a sister shares sensitive information meant to be kept private, it doesn’t just breach trust; it shakes the foundation of their entire relationship. The OP's emotional turmoil is palpable, and her hesitance to move past the incident highlights the complexity of familial ties. It's not simply about the act itself but the ripple effects it creates.

This isn't just a case of saying 'I'm sorry' and moving on. The sister's attempts at making amends may feel insincere to the OP, who likely grapples with whether forgiveness means condoning her sister's actions. It’s a classic case of wanting to heal while feeling the weight of the betrayal lingering heavily in the air.

OP’s sister didn’t just slip up once, she shared the exact private relationship details OP asked her to keep locked up.

NTA - Trust is hard to rebuild after it's broken. Your feelings are valid, and forgiveness takes time.

Comment from u/coffeeholic77

Forgiveness is a choice, and it's okay if you're not ready to forgive yet. Your sister needs to understand the gravity of her actions.

Comment from u/wanderlust_dreamer

NAH - It's understandable to struggle with forgiveness, especially after a breach of trust. Take your time to heal.

The apology sounds good on paper, but OP says the damage was already done when her sister exaggerated the story to make her look worse.

You're definitely NTA here. Forgiveness isn't easy, especially when someone close to you has hurt you deeply.

Comment from u/musiclover123

INFO - Have you tried sitting down with your sister and expressing how you still feel? Communication might help both of you understand each other better.

It’s also like the AITA where a sister’s secret fling with the ex led another woman to skip her wedding.

Your feelings are valid. It's okay to take your time with forgiveness. Don't rush the process.

Even when her sister shows up and is supportive in other parts of life, OP still can’t trust her with anything personal again.

NTA - Forgiveness is a personal journey, and it's okay to need time to heal. Your sister needs to respect your feelings and give you space.

Comment from u/teatime_connoisseur

NAH - It's tough to forgive when you've been hurt deeply. Your sister needs to understand that healing takes time.

Comment from u/adventure_seeker99

NTA - Trust is a fragile thing. It's okay to set boundaries and take your time with forgiveness.

So when the sister keeps trying to mend things with repeated apologies and “I’ve changed” energy, OP has to decide whether forgiveness is possible or just another betrayal waiting to happen.

Comment from u/mountainclimber22

NTA - Forgiveness is a process, and it's okay to still be hurt by past actions. Take the time you need to heal and rebuild trust.
