TRP helped me a lot especially at passing shit tests and fighting fire with fire, I dont want to start as "There is a girl...", its not something special, just something I cant quite understand, so I need opinions.

A few months ago I met a girl through some mutual friends, we have many common things but she was in a LTR at that moment so I didnt care much, but a few days ago we started chatting again and Ive learned she has broke up, we met yesterday, she said things like how she missed me and wants to do shit together, some of them requires her to come at my place, so it was going really nice, but then she mentioned her homemates brother, an underage boy is interested in her and invited him to join us, I mean it was impossible for me to see a kids presence as a competition so it was ok. But now, I feel like she is ghosting me on purpose, texted me this morning, I replied and invited her over as we planned yesterday, its been hours and no reply (Ofc I never text twice) The questions are, is this a kind of twisted test? I cant even think losing against a kid but do you think this is actually possible?

Sorry for the long post, any view is appreciated.
