I (25F) live with my roommate, Jenna (24F), who I met through a friend. We split rent and utilities 50/50 and mostly get along, but I’ve noticed some of my jewelry and makeup items have gone missing over the last few months.

I didn’t want to accuse her outright, so I came up with a plan. I bought a $15 fake engagement ring on Amazon that looks like a real diamond. I left it on the bathroom counter before I went to work and made a note of where it was placed.

When I came home, it was gone. I asked Jenna if she saw it and she said no. I pressed a bit harder, and she got defensive. So I said, “That’s odd. It was my late grandmother’s, and it’s worth about $5,000.”

Suddenly, Jenna “found” it in the couch cushions.

I told her the truth, that it was fake and I was testing her because stuff has been going missing. She flipped out. Said I was manipulative and paranoid, and that I “entrapped” her.

Now she wants to move out and is telling mutual friends I’m toxic and can’t be trusted.

AITA for baiting my roommate with a fake ring?
