Wow, everyone knows that drama tends to erupt when someone is planning a wedding, but this drama feels like a movie! We're used to the stories of someone wearing white other than the bride, like a narcissist mother-in-law or a jealous ex. We've also heard the ones where the groom or groomsmen drank one too many and really put a damper on the shindig. But this is a whole new level! 

 

Here we have betrayal, glow-ups, true love, entitled love, adult tantrums, and more. At least the husband of the starring role is a green flag in our books—we love a supportive king!

  • Long story short, the bride was marrying the brother of an ex of her's, and the ex of her's cheated on her with the woman he married. They didn't invite her to their wedding because they sound like horrible people and didn't want to have to look at the face they both betrayed. But now, this bride was marrying into the family and wow did this entitled cheater sister-in-law through a fit when she got served the same medicine. Ya get what ya give, babygirl.

  • "AITA for not inviting my SIL to my wedding bc i was not invited to hers."

    I, 32f am getting married to the loml, 35m in a few months. Everything has been nothing but perfect until the guest list was finalized. We're having an intimate wedding with only 75 guests including family and friends (we both come from big fams). Although

  • we only have 75, it still seems like a lot in terms of preparations. I also have at sister and my best friend flying from overseas to be part of my special day. My fiance and I have talked about my FSIL (his brother's wife) and told

  • now that she's married to my FBIL, so i have no idea how they even met or got together. And also, they had been together before I met my fiance, I was already in the picture when they got engaged, I was genuinely happy for them but lowkey hoping

  • she "didnt feel comfortable" having me there. (This will be important later) But i respected that. They went throguh with their wedding without drama from me or my fiance. I was so glad that he backed me up to tell them

  • politely that he will not sit at a table where his girlfriend is not welcome. So even he didnt come. I felt really bad and guilty but he already made up his mind about staying with me, but i didnt know that during this time he was already planning the

  • the get go he told me he supports whatever my decision is. I told him that it would just make things awkward if i invited her. She made every possible way to tell me she doesnt want around her, so it would make sense if we didnt bother putting her on the invitation.

  • After we sent out the invitation to his BROTHER, he called my fiance 10 mins later, but as soon as he answered, IT WAS HER that called my fiance, using her husbands phone!!!!

  • She started yelling and yapping about why her name is not on it, or even a +1 included. My fiance told her that it didnt make sense that she hates me but will be invited to our wedding so it was best to not out her in the invitation. SHE. WENT OFF.

  • My fiance didnt even need to put the phone on speaker because i can hear her screaming her lungs out just by standing. next to him. She then proceeds to saying how she is his wife now and wherever he goes, she goes. I couldnt believe

  • what i was hearing, my fiance then asked her if that was why I wasnt invited to the their wedding, because i was just the girlfriend at the time. crickets

  • She kept going on about how pathetic and petty I AM for not inviting her or putting her on my bachelorette. Yet she kept giving me the impression that she out!

  • My fiance is now seeing this girl for who she really is and he told me that not inviting her is for the best and we should stick to it. But what im worried about is his brother and what he would say. I dont wanna ruin their relationship and i

  • want him to be there for his brothers special day. but at the same time this is our wedding. And btw his brother will not be part of his groomsmen or best man because he can only be there on the day and wont be available for rehearsals, bucks night

  • etc due to an operation recovery. Just incase yall wonder why we're only telling him now. I just know for a fact that this girl will s k the life out of me and my fiance during our wedding, and she literally just proved it by the way she acted.

  • SitcomKid411 NTA. She sounds like a walking dumpster fire. Actions have consequences and she set the tone for the non-relationship. Have your day your way. Your finance is on board, so carry on.

  • Wrong-Sink-9554 OP Thank you so much! I also thought how she can act this way when she literally was the one that did me wrong. I was never mean or ride to her when i found out she was with my fiance's brother. I even told my fiance i was thankful for what happened bc i wouldnt have met him if i stayed with the wrong person. I was grateful for everything so I knew

  • how to view life in a positive way. I genuinely moved on in my life but she acts like she's still living with her nightmares. She never even apologized for being a home wrecker. So im guessing me being finally happy and loved by someone whom i trust would never cheat on me is her backfire.

  • Travelling Wench People who throw tantrums to get their own way, have got their own way by throwing tantrums. She can't expect to treat you one way and for you to sk it up. Absolutely not the , tell her she is just being treated the way she treats others.
