Getting married is a huge event in anyone’s life, and you want to make sure that everything goes smoothly.

What would you do if your sister was going to marry someone who you used to work with, and then just a few days before the wedding, she asked you if you had ever had a romantic relationship with him, even though you told her long ago that you didn’t?

That is what happened to the young lady in this story, and even after confirming that she didn’t, her sister said that she couldn’t come to the wedding unless she let her go through all of her phone records as proof. Now she is hurt and upset, so she is refusing to hand over her phone or attend the wedding.

Her sister is having trust issues with her fiancé, and that is who she should be addressing this with. Read through the full story below and see if you agree.

AITA for refusing to attend my sister’s wedding after she wanted me to prove I didn’t have anything with her fiancé?

I (26F) have always been close with my older sister (29F).

What an exciting event.

She’s getting married in about a month to her fiancé who she has been with for four years now.

But before they met, I worked at the same company as him for almost two years and we were friendly coworkers, we normally grabbed lunch with other colleagues and occasionally texted about work. Nothing romantic ever happened between us.

And now the drama begins.

Fast forward a year, he and my sister meet through mutual friends. When she found out we already knew each other, she laughed it off and even joked that I should tell her if he had any embarrassing stories from work.

Well, everything was fine until a few weeks ago when she called me crying, saying she’d found old messages between him and me from years ago.

I can see why her sister is asking about this, even if there was never anything romantic there.

One message where he told me “I missed you today” and me also telling him ‘I wished you came to work today” the reason for those message were due to the fact that we usually help each other with tasks at work and cover for each other.

Besides that we only talked about work, shared memes, work gossip, and one other conversation where he thanked me for helping him prepare for a presentation, which is something we usually do.

Her sister clearly doesn’t trust her.

She asked me if I had ever had feelings for him. I said no, because I genuinely didn’t and never saw him that way.

Then she asked if I’d be willing to let her read through my old phone backups and social media messages to see the context for those messages for her peace of mind.

There is nothing wrong with letting her sister look, but it is a little weird.

I laughed because I thought she was joking or better still, let her go through his phone not mine and I started getting annoyed when she kept insisting I allow her go through my phone.

She said if I had nothing to hide, I shouldn’t have a problem proving it and her friends suggested the same thing and that if we did this one thing, it would help avoid future drama before the wedding.

This is drama between her sister and the guy.

I refused immediately. Not because there’s anything to find, but because I think it’s an insane invasion of privacy.

Apparently that made me look guilty in a way but I just wanted her to go through his phone instead and not mine.

Her sister is just not letting this go.

She still asks why won’t I clear my name and give it a rest? This made me even more upset because she’s focusing on the wrong person and what name do I need to clear?

She told my mom about the whole thing and her response was that I’m being too prideful over little issues.

But she doesn’t mind making her sister think she doesn’t trust her?

The final straw was when my sister said she didn’t feel comfortable having me at the wedding unless I handed over my phone first, so we sort it out once and for all. But why can’t she ask her fiancé? Her response was “I don’t want him to think that I don’t trust him”

So I told her I wouldn’t be attending at all and that she could have the wedding she wanted without me there. Let her go through his phone and not mine.

AITA?

This is a crazy situation, and I certainly don’t blame her for not wanting to hand her phone over to her sister. This is a problem between the sister and her fiancé. Sadly, it is causing a lot of drama.

Her sister has some real trust issues, and she is smart to not give in to her demands. Even if she handed over her phone, I doubt that would be the end of it.

If her sister doesn’t trust her fiancé, then she should be talking to him about it. End of story.
