Competitive toward my friend

How can I stop feeling competitive toward my friend?

Ever since I was a kid, I’ve been quite an individual and never took it as flattery if someone “copied” me. I’ve definitely mellowed with age, but that competitive spirit is bubbling up right now towards one of my best friends.

Our hobbies, interests, and fashion tastes have always been distinct from each other. Recently, her tastes are changing and are more similar to mine. I’ve had pretty much the same tastes my whole life, and I always feel almost territorial when others change their tastes to mine. It’s very petty and childish, I know.

It’s not that I can’t stand to not be unique. I have friends who share my same interests. The difference is that those friends were already into the same things as me when we became friends.

My best friend was very different from me and is getting more similar now in fashion and things like what books we like to read etc.

What’s even worse is that I’m in the middle of planning my wedding according to these aesthetics that I’ve always held. She expects to get engaged soon, so she’s already planning some bridal outfits and activities that she wants to do, and it’s so similar to mine 😭 I want to just be excited for her, but it just bugs me so much.

What are some ways I can train myself out of this competitive nature? I don’t want to feel so bratty and petty over something so silly. Telling myself to get over it just isn’t working.
