What's worse than suddenly bumping into an ex unannounced… 

Try bumping into them at a wedding ceremony, except this time, it's your parents tying the knot… and now, congratulations, you're about to become newlywed stepsiblings. Yep. Let that sink in. Talk about a plot twist no rom-com ever dared to touch. One minute you're avoiding awkward glances at family brunches, the next you're in a legally bound family tree with the person who once ghosted you after "a really great time." Fabulous.

Well - that throws a bit of a spanner in the works now, doesn't it? The fact is that you're exes for whatever reason: whether he gave you the dreaded ick with one badly-timed baby voice, or whether he shattered your heart into emotional confetti, an ex is an ex. Your dream of walking down the aisle with him by your side definitely did not go as planned…

After years of sneaking around just to be under the same roof, you are now forced to live under one! Courtesy of your suddenly star-crossed parents.

  • So in this case, the question is: how do you sit your father down and tell him that if he goes through with marrying your ex-boyfriend's mom, you will a.) not be in attendance and b.) possibly enter full exile-mode right out of his life, because he has totally ruined yours!

    reetahroo He didn't tell you they were dating which means he knows what a mess she was in your relationship. NTA. He can marry who he wants and you can ignore and act like she doesn't exist

    OfluffytheOferocious NTA. Your ex-boyfriend is now your stepbrother. I think that's reason enough to not want to be there.

    jkeefy You are NTA. No one is TA for not wanting to attend a wedding. Attendance is not mandatory for anyone. It's called an invite for a reason.

    WinnieTheShark I feel like him not informing you until it's too big to avoid is a very obvious admission of guilt.

    Andromeda081 He deserves to be happy, but this is messy for you on a personal level. You're entitled not to be around a cr py ex and his family you don't like. You're entitled to tell him & aunt this is a hard boundary for you.

    Feeling Week6757 Is your ex gonna be there? That could be a deciding factor also. How dysfunctional could the whole event be? Are they expecting one happy family?

    Ruthless_Bunny Tell your dad, "considering that the last time we talked there was no mention of dating or anything else, I'm shocked. I need to process this. I'll get back to you."

    LolaSupreme19 NTA. Your dad didn't loop you in about his relationship with your ex's mom. Since he sprung it on you, he shouldn't be surprised by your reaction.
