Should I just text him first?

So I just turned 17 and he's about to turn 18. We've been talking for a little over 2 months now & last friday we hung out at his house. I'm pretty sure he's not the relationship type and I'm not either but needless to say we did almost everything but sex that night even though it was really the first time we've ever hung out alone. We used to text every day and he would usually text me first but this week we've both been sick and i've texted him on two different occasions but it hasn't been like it normally is. The last time he texted me was wednesday but then he never replied after I texted him twice.. Do you think he's done w/ me now or should I just text him first? As far as developing an actual relationship, I'm not looking to force anything so I'm just going with the flow. Hahah alright well thanks ahead (:
