Talking with a chick for say 2 months now. She's been pretty into me and I often reciprocated her energy. Recently she's been hardly putting in effort communication-wise, 2 word texts and shit. Denied my last meet-up request, with a valid reason though.

She's fairly introverted so my two guesses are either; She doesn't care too much for phone communication, or she thinks I'm invested enough she doesn't have to care.

From other posts I figure the most common answer is the minimal effort Soft-Next. There's something on the sideboard too about if a girl isn't investing enough, challenge her on it. However I don't know if that's a good idea here, or what should be said.

I don't care if she's not great at responding, but I'm not going to waste time to get meetups denied. So to the question to get general knowledge from this experience, what are some methods yall use to feel it out handle this?
