Mom took my perfume to give to my sibling

My mom grabbed two of my expensive perfumes and said she was giving them to my sibling—without asking first—and I honestly don’t know how to feel about it.

I’ve never really posted about my family before, but something happened today that left me really confused and a bit hurt. I have a younger sibling, five years younger than me, who is now 30. They’ve got a great job, make good money, own their own place, and live with their partner. Despite being fully independent, my mom still treats them like they’re a teenager who needs constant help. She makes them meals and delivers them multiple times a month, sends money, and buys expensive gifts—even though my sibling probably earns more than most people I know.

I’ve always noticed the favoritism, but I let it slide. I’m also doing fine financially, and I’ve never expected help from my parents. I guess I just got used to it being that way. But today something happened that pushed a boundary.

My mom came over for dinner and to see our kids. While we were chatting in the bathroom (I was folding towels), she looked at my new perfume display. I love perfume, and over the years I’ve collected a few really nice ones—YSL, Tom Ford, Burberry—some were gifts from my husband, and a few I’ve bought myself for special occasions. Most of them are barely used because I save them for when I want to feel a bit extra.

Without asking, she grabbed two bottles and said she was going to give them to my sibling. Just like that. “You don’t really use these anyway,” she said, while putting them in her bag. I was so taken aback I barely knew what to say. I finally told her they were gifts from my husband and that he’d be upset if I gave them away. She seemed a bit surprised but didn’t argue. Still, I couldn’t shake how weird it was.

It’s not even about the perfume, really. My sibling can easily afford their own. It’s the fact that my mom saw my things, assumed I didn’t need them, and decided to give them away without even asking. It made me feel like I don’t matter as much. Like it’s always about what my sibling wants, even if it comes at my expense.

My husband thinks her behavior is really out of line. He’s always said the way she treats us differently is strange, but I’ve just brushed it off as “that’s just how she is.” Now I’m not so sure.

Has anyone else experienced this kind of one-sided dynamic with a parent? Is this normal and I’m overreacting, or is this as odd as it feels?
