Am I missing something?

I, female, am on tinder to find a friends with benefits. Match with a guy, we hit it off, we're looking for the same thing. A couple days we have a vibe check date, awesome goes really well, a few days later we meet at his place and hook up. Both very happy and satisfied. I express in no uncertain terms that I want to do this again, he agrees enthusiastically.

Now, we had been texting quite a lot. But that kind of comes to a halt. Two days later I ask "hay what's up? If you're not interested that is cool." he is adiment that he is still interested, great. More days pass, not a lot of contact. I ask again, and get a he same enthusiastic answer. This has never happened before. If I had gotten a luke warm answer or something, I could've taken the hint, but he is enthusiastically expressing wanting to see me again.

Now, is he keeping me as an option or is he very scared or hurting my feelings? Should I just write him off?
