Should I text him again?

I dated this guy for three months before and felt it wasn't moving forward. We suppose to catch a movie together afterwork on a Wednesday but none of us texted each other thro that week, til Wednesday I asked 'been busy?'. He didn't reply til Saturday asking 'how's your Saturday going?' I was kinda pissed at him so I didn't reply and cut him off. 
Last week my friend encouraged me to text him again. Very surprisingly he texted me back. But now it's kinda died again, not sure if I should text him again? Or maybe he is not even interested anymore? What would you girls do in this case 
Ps: he is a very dry texter, typical topic killer lol
