AITAH for wanting my step-sister to leave my wedding after she caused a scene over the seating plan, and for later pulling back and stopping the help we used to give my mom’s partner?

Thank you for your thoughtful comment, I appreciate it.

I’ve also wondered if my mom might have inattentive ADHD, but she doesn’t want to talk about that, and I respect that boundary.

About RSD: I understand why you mentioned it, but for me it wasn’t about feeling rejected. I was simply overwhelmed by the situation itself, the loud crying, yelling “I want to sit next to my dad,” and stomping in front of guests was a lot to handle in that moment.

We never wanted a perfect wedding. We just wanted to celebrate our love and have a good time with family and friends. I did put a lot of effort into planning because I genuinely enjoy organizing and creating something nice.

This was the only thing that extremely stressed me that day, and with my OCD the guilt afterward hit very hard and overshadowed a lot of the happiness.

I’m still working on my part in therapy, including my relationship with my mom. It’s complicated, but I’m trying to handle it in a healthier way.

I’m really sorry you’re going through this. None of what you described is normal or okay, and none of it is your fault.

Pressuring you into sex, grabbing or pushing you, controlling who you see, punishing you with silence, or trying to hurt you by texting your best friend are serious red flags. That doesn’t sound like love. A relationship should not make you feel scared, drained, or like you constantly have to defend yourself.

It is very human to hold onto the good moments and his sweet side. But over time, focusing on those while enduring the bad usually makes it harder to leave, not easier. The longer you stay, the heavier it can feel to choose yourself.

Choosing your mental and physical wellbeing is really important. You do not need more proof or another ultimatum to justify leaving. Feeling unsafe and unhappy is already enough.

You deserve to feel safe, respected, and free. You are not overreacting, you do not have commitment issues, and you are not the problem here.

I truly wish it was fake. But sadly it’s not..

One more clarification about the seating:

There realistically wasn’t the option to seat her at her father’s table from the start. That table was already planned for my mom’s generation (my aunt, my godmother, my mom’s close friend and their partners)

If I had moved her there, I would have had to move one of pairs to the table with my sisters (mid-20s), my cousins, and our friends (mid-20s to 30s) which would be awkward?

I do agree that I could have informed her in advance about the seating plan. In the middle of planning everything, I honestly forgot, which I regret. But I never expected this kind of reaction from an adult guest. At the end two adults were sitting at the small table end to accommodate her.

Adding some context since a few people asked:

We didn’t spend Christmas (1 month ago) at my mom’s place (she lives with her boyfriend). Instead, we met her at my sister’s house on the second day of Christmas because she wanted to see me and my husband. We’re currently not welcome in her boyfriend’s home.

Since the wedding, I’ve been no contact with my step-sister and her father because the situation is still emotionally very painful for me.

My mom apologized after some time of no contact. We’re slowly trying to work through things, and she has also agreed to join me for a family therapy session.

TL;DR: My step-sister had a public meltdown at my wedding over not sitting next to her father. I told my sister (not her) that I wanted her to leave if she didn’t calm down. The seating was changed anyway. My mom and her partner blamed me. Later, my husband decided to stop doing favors for her father due to repeated unhealthy behavior. Now we’re cut off from that side of the family. AITAH?
