Text etiquette/ interest

Hey guys!

I am keeping another guy under wraps I met just because it is new, I really like him, and I don't want to screw anything up. We met on an internet site a while back, adam4adam of all places. Don't ask. I'll explain later. We became myspace friends a few days later, then we chat back and forth when he is on AIM. He has been messaging me about once a week on myspace. I always reply back. This past Thursday after he sent me a myspace message saying he was coming to my city that night I wrote him back and gave him my cell phone number as a hint. We chatted via text Thursday night. Friday night he texted me asking what I was up to when I was out with friends and wrote back. Saturday we finally hung out and met in person. We texted back and forth that night. Sunday afternoon he texted me while I was out and about the time I went to bed.

So now that I have vaguely talked about our conversations my question is what should I say to him?

I know it is more than my turn to text him, so I want to do that.

We're just friends right now, nothing more. I haven't been to his house or done anything beyond given him a hug, so don't get your hopes up.

So when should I text him? What should I say? Should I just do a simple "what's up?" Should I randomly write him about a "random thought" that I had about something like I tend to do with friends? Should I text him after I make a delicious meal or recipe because we both really enjoy cooking and kind of brag?

Thanks for your help!
