One of the greatest things about Odyssey is the fact that you can write about anything that you want and share your opinion with hundreds of thousands of people. One of the worst things is that sometimes these opinions are a little insane. Take the recently viral article, "You May Have Worn The Prom Dress With Him, But I Get To Wear The Wedding Dress ", written by Victoria Higgins, bride-to-be. If the tone of the title doesn't tip you off to where she is going with this piece, allow me to briefly summarize: she's mad at her fiance's high school ex-girlfriend for...simply being his ex.
Now trust me, I completely understand hating your significant other's ex if they cheated on, sexually assaulted, or physically hurt your loved one. But that really doesn't seem to be the case with Higgins' argument. As far as I can tell, she's mad at this poor girl because she had a previous relationship with her fiance, which is not only completely unfair but also a little bit crazy.
I'm not sure if you were aware Victoria, but dating is a part of life. By the time a person gets married, they will have loved, dated or even just liked multiple people in their lifetime. This is nothing to get upset over, and it's certainly not a reason to write a braggadocious article about how much better you are than your fiance's ex because you're the one marrying him. It's cringe-worthy, petty, and most of all, immature. Honestly, I was surprised to find you're not still in high school because your article is some next-level high school drama bs.
The past is the past for a reason. An ex is an ex for a reason. You don't need to rub it in anyone's face. But obviously, since you feel the need to do so, I'm going to go ahead and say I don't think you should be getting married. You're clearly not ready.
If spending the rest of your life with your fiance isn't enough, leading you to attack his ex in an article that could easily be traced back to her, then you're not ready for the lifetime commitment of marriage. Marriage should be about the two of you, not the two of you plus his ex. You should be looking forward to your future together, not back at what could have been.
The fact that you can't move on says a lot more about you and your relationship than it does about this poor girl and her past relationship with your fiance. You have no reason to be jealous because, as you yourself pointed out, "he is [yours] now, and [you] get to cherish him forever."
But don't count your chickens before they hatch Victoria, you're not married yet. In fact, I really hope that since your article has gone viral he's read it and seriously reconsidered your relationship. If I were him I would be running far, far away from you.
You call your fiance's ex out for using him as a "popularity appearance" but isn't that exactly what you're doing right now? You're putting your relationship third, right after juvenile jealousy and your own self-importance. I'm sure you thought you were making a great argument, showing your fiance why you're the best girl for him, but all you really showed is that you're still just a girl, too caught up with popularity and other petty bs to really understand the gravity of what it means to be engaged.
Call off the wedding and call a therapist. If he's ready to marry you—heaven help him—it means he's clearly moved on from his ex, so why can't you?
