LTR and I are seniors in college. There are a couple sophomores in her pride group (kinda like a sorority) that I joked around with my LTR about being in love with. I've only met them in passing but I make these jokes because they're both really pretty. I added them on fb a couple days ago and made a comment to my SO about it; she thought I was joking and said it was creepy. Whatever, I ignore. Then she texts me today and says something along the lines of "I thought you were just joking, that really is creepy. I'm not okay with it."

I immediately recognize the shit test but am unsure how to respond. Agree and amplify just pisses her off (doesn't like when I make jokes when she's upset), and I sure as hell know better than to try and defend myself. That basically leaves ignoring the shit test but she'll just act passive aggressive until I see her in person at which point she'll bring it up again. Any advice?
