AITA for telling my brother not to be so involved in his GF’s cycle?

Family dynamics can be tricky, especially when it comes to relationships and personal boundaries. I never thought I’d find myself questioning my younger brother’s way of showing love to his girlfriend, but here we are. What started as a sweet and thoughtful habit struck me as wasteful, obsessive, and maybe even a little creepy. Now, after I spoke up, I’m the one being painted as the bad guy, and I’m left wondering if I crossed a line.

Time to see how Reddit weighs in on this drama.

At the end of the day, I know my brother means well, and Michelle clearly doesn’t see an issue with his behavior. But to me, it feels like he’s gone overboard, and I just couldn’t keep my thoughts to myself. Now, Michelle has told me to stay out of their relationship, my brother won’t talk to me, and I’m left questioning whether I was being protective or just meddling. So, AITA for stepping in where maybe I shouldn’t have?
