My Sister Who Regressed Wants My Fiance

Okay, so you know how life just loves to throw curveballs? Like, you think you’ve got it all figured out – career on track, found the one, wedding Pinterest board looking amazing – and then BAM! Something totally unexpected happens. Something… well, a little bit crazy.
Let me introduce you to the crazy. It's my sister, Sarah. (Names changed to protect the… well, you’ll see.) She’s always been a bit… quirky. But lately? Quirky has escalated to, like, a whole new level. A level I’m calling “Operation: Get My Life Back, Stat!”
See, Sarah has, um, regressed. Yeah, I know, sounds like something out of a bad sitcom, right? But trust me, it's my reality. She’s acting like… like she’s ten years old again. Pigtails, sparkly unicorn backpack, the whole shebang.
Must Read
At first, it was almost… cute? (Okay, maybe for like, five minutes). We all thought it was a phase, a weird coping mechanism for stress, maybe? But weeks later, she’s still trading her vegetables for dessert and asking to be tucked into bed. And… wait for it… developing a major crush on my fiancé, David.
Yes, you read that right. My fiancé. The guy I’m supposed to be walking down the aisle with in, like, six months. The guy who makes the best Sunday pancakes. The guy who… is now apparently the object of my little sister’s (regressed) affection.

I'm not even joking. She follows him around, calls him “Davey,” and even made him a construction paper heart that said, “Davey is the bestest!” Bestest? Seriously? I haven’t heard that word since, like, actual third grade. I'm mortified.
Is this my life? Is this REALLY happening? Am I living in some bizarre rom-com where the quirky sister tries to steal the groom? I keep waiting for Ashton Kutcher to jump out and tell me I'm being Punk'd. But alas, no such luck.
And the worst part? David is being… well, David. He’s naturally a super nice guy, so he’s just being friendly and patient with her. Which, I get. I appreciate. But… ugh! Doesn't he see the goo-goo eyes? Doesn't he notice the constant clinging? Maybe I'm overreacting, but is he completely oblivious?

He keeps saying things like, “She’s just going through a tough time. We need to be supportive.” Which, yeah, totally agree. But supportive doesn’t mean letting her braid his hair and demanding he read her bedtime stories! Where does it end?
I’ve tried talking to her, of course. But it’s like talking to a wall… a wall covered in Lisa Frank stickers. She just giggles and says, "Davey's my friend!" And then she asks me to do her hair, but only in pigtails, mind you!

I’ve even considered talking to a therapist. Not just for Sarah, but for me too! This situation is seriously stressing me out. My wedding dress fitting is next month, and instead of worrying about alterations, I'm strategizing how to keep my sister away from my future husband. Talk about pre-wedding jitters!
The Big Question: What Do I Do?
So, I’m at a loss. Do I stage an intervention? Do I hire a child psychologist (for my adult sister)? Do I just lock David in a room until the wedding day? (Okay, maybe not that last one, but the thought has crossed my mind!).
I need advice! Seriously. Any tips on dealing with a regressed sibling who has a crush on your fiancé would be greatly appreciated. Send help! And maybe wine. Lots of wine.

Maybe I should just elope. Just kidding! (…Maybe?)
The wedding is still on, for now. But I’m starting to feel like I need to hire a bodyguard. Not for me, but for David. To protect him from… Sarah's undying (and slightly creepy) devotion.
Wish me luck. I’m going to need it.
