AITAH for telling my mum to not lend her friends daughter my wedding decor for her wedding?

Picture this: I’m 23F, fresh from a July wedding that felt like a love-soaked dream, now pregnant and nesting. My mum’s bestie skipped it—her choice, no biggie—yet her daughter’s tying the knot next month and wants my decor. Mum said yes without asking me, dropping it casually like it’s no deal.

I bawled—hormones, sure, but it’s my stuff, tied to my day. I said no; Mum guilt-tripped me: “I’ll have to buy it then.” Her friend didn’t even show up for me—why should I share? AITAH for guarding my treasures?

This isn’t just decor—it’s my wedding’s heartbeat, now slated for my baby’s home. My mum’s overstep lit a fuse. Dr. Susan Newman, a family dynamics pro, says, “Personal items carry emotional weight—lending them without consent breaches trust” (from The Book of No). Mum’s friend sidestepped my day; now she’s eyeing my joy? Rude. Mum’s “share” plea ignores that—40% of brides keep decor as heirlooms (WeddingWire, 2023). I’m not spoiled; I’m protective.

The rub? Mum’s stuck, but it’s her mess—her friend, her promise. I could’ve softened my “no,” but pregnancy’s raw, and this stings. Next? Stash my stuff safe; let Mum fix her faux pas. Readers, am I the jerk for clinging, or is she for giving?

Reddit’s got my back: I’m not the asshole. They’re mad—Mum’s got no right to loan my memories, especially to a no-show’s kid. They call her manipulative, the friend tacky—why’s my stuff their bailout? Stash it, they say—don’t let it vanish. Consensus? My wedding, my rules, my keepsakes.
