A girl that I have been courting/sexing likes to text me random shit and then not reply when I finally do reply.

Just yesterday:

Her:"Yo, I found your entire shirt" (that I had left at her place Me:"nice, take care of my baby" (it's a bro tank, inside joke)

She didn't reply. In fact, she rarely does. Should I ignore texts like these? How should I react? I'd like to keep texting for only setting dates but I never really know how to respond to shit like this
