Anyone else ever experience this, or is it just me?

I’m totally obsessed with this girl in a very “I want to be her” kind of way. I have no idea why. She’s my husband’s friend’s wife. So like, it’s not like a romantic thing at all. I just feel like I’m so jealous of her and it’s all for no reason. Some of the things she has that I find myself envious of, are things I don’t even want. I feel like I’m constantly checking her social media pages basically just for “ideas” of what to do, how to behave, etc.

I feel like it’s the equivalent of how someone would follow and obsess over a celebrity. But... she’s not a celebrity, she’s a person I know in real life?

Am I crazy or has anyone else been through this??
