Sister excludes me from wedding, expects me at engagement party - AITA?

A 29-year-old woman thought her sister’s engagement would be an easy, happy moment. Spoiler: it was not. The closer she tried to get to the celebration, the more it felt like her place in her sister’s life had quietly been “downgraded” to an accessory for later events.

Her sister, 31, planned a small, intimate wedding with just immediate family and left her out completely, using the “we want to keep it small” excuse. Now the same sister is planning a bigger engagement party and expects her to show up and help with preparations, like none of the wedding sting ever happened.

So the question is not just whether she should attend, it’s whether she should reward being excluded.

Original Post

So I'm a 29F and my sister, 31F, recently got engaged. We've always been extremely close, and I was excited to celebrate this special time with her.

However, things took a turn when she decided to have a small, intimate wedding with just immediate family. She chose not to invite me, claiming she wanted to keep it small.

For background, I've always been there for her through thick and thin, and this exclusion really hurt me. Fast forward to now, she's planning a big engagement party and expects me to attend and help with the preparations.

I feel conflicted. On one hand, she's my sister, and I want to support her.

On the other hand, her decision to exclude me from her wedding feels like a betrayal of our close bond. I can't shake off the feeling of being left out and now being expected to play a role in celebrating her engagement.

So AITA?

The Sibling Rivalry at Play

This situation is a classic case of sibling dynamics gone awry. The OP feels sidelined by her sister’s decision to exclude her from the wedding, which naturally leads to feelings of resentment.

When family members pick and choose who gets to share in milestone moments, it creates a fracture that can be hard to mend. The OP's decision to skip the engagement party is a significant one, fueled by a sense of betrayal. This is where many readers resonate: they see the emotional struggle and understand that family ties don’t always guarantee support or inclusion.

When OP realizes her sister chose “immediate family” for the wedding but still wants her around for the engagement party, the hurt stops being subtle.

NTA - That's a tough spot to be in. Your sister excluding you from her wedding but expecting you to be there for the engagement party seems unfair. It's understandable that you feel hurt and conflicted.

That's tough... I feel like your sister should've at least explained her decision to you. Family dynamics can be so complicated. NTA, I think you're justified in feeling hurt.

YTA - Family events can be emotional, but it sounds like your sister may have had valid reasons for keeping her wedding small. It might be important to have an open conversation with her about your feelings.

Comment from u/Whimsical_Waffle

Wow, that must've been really painful. I can see why you're conflicted about attending the party. Ngl, your sister should've handled the situation better. NTA.

OP keeps replaying how she’s been there for her sister “through thick and thin,” while her sister acts like this wedding decision was no big deal.

Comment from u/Curious_Banana42

It's understandable to feel hurt and conflicted. NAH, but your feelings are totally valid.

This feels similar to a sister excluding her from a family photoshoot and party, then debating whether to refuse to attend.

NTA - Your sister should have communicated better with you. Emotional situations like this are always tough, but your feelings are valid in this situation.

Comment from u/ThunderousSunflower

I get why you're hurt, but family events can be messy. Maybe try talking to your sister about how you feel before making a decision. It's a tough spot to be in, NTA.

That’s when the engagement party invitation turns into pressure, because OP is expected to help prep after getting cut from the wedding.
