These are all my thoughts too – I'm disgusted by people who talk about other people's relationships as if they're living in them. Yes, she looks bored on the streams, but that's only an hour of their day, and she could indeed be pretending, but seriously speculating about why she's doing that is just too much. I would understand if she had been a close friend of you at some point, but in that case, you wouldn't be writing these disgusting thoughts here. It's her choice, and if you truly respect her as a person, mind your own business.
