Had a GF do this to me in high school. The funny part is I passed the little “test”. Convo got flirty, I said I have a GF, and to keep this platonic. GF still got pissed.

This was also a classic case of projection, as the girl ended up branch swinging. Take a long, hard look at your relationship and don’t get too attached. Personably, I’d immediately downgrade to plate. Make this known to her but don’t give reasons why.

As for the FB girl, don’t respond. If it is that girl your dating, there’s really no right answer. If it’s not, any girl with a sketchy FB profile and cold approaching on FB is NOT the type of girl that is worth your time. No good can come of this regardless. And it’s not important finding out which situation it is... be stoic and careless.
