Question about my fwb...I'm confused!!!?

So been doing a fwb with this guy since February...we hung out a week and a half ago and it was really, really awesome, like not even all about . We watched movies, played a board game (lol), cuddled, talked on a real personal level and held hands. So we kept in touch the next couple days, texted while i was a work but he just kind of disappeared after he told me he wanted to see me a lot more. I don't get what his deal is because he was acting very interested.
