I have no clue what I'm doing and what I'm supposed to be doing

[Funf]

I've gone out with a guy on 4 dates so far and we have the 5th scheduled a few days from now. We really click when we're together. It seems like we just "get each other" if that makes any sense. The most physical that we've been is just making out and spending the night together without sex. I know that it's early, but I really like spending time with him and so far I like what I see. The problem is that I have only been in dysfunctional and unhealthy relationships in the past. I don't know what I'm supposed to be doing in the interim. Am I supposed to be sending cute and flirty texts? Short emails? Posting flirty stuff on his Facebook? I know this is a dumb question but I seriously don't know. If it matters, he doesn't do any of that stuff, but I don't know if he wants me to take the lead. I don't want to come off as disinterested and passive, because I'm not, but at the same time I don't want to be overbearing and clingy.
