Anxiety, boundaries and expectations?

[canadianMrs.]

I'm new here, from MLC. H and I have been in MC since December, and have just started dating each other (exclusively).
We are living in different cities (hour and bit apart) but he is here at least every other day for a visit. The last couple of days I've had mixed feelings about were we are, which suprised me. I worked hard for this. I'm afraid to be hurt/rejected again.
As well, H has said he realizes he is not a good communicator/puts walls up, and that is what we need to work on for a successful marriage. While I agree, I need way more than that, and I've always been able to express myself. How do I let him know all that I would need with out overwhelming him.
Plus, over the months we've become friends, and text frequently through the day. We're still doing this, but I need more to build on our connection. With H's work schedule and the kids activites, scheduling dates is hard. I need to know what to do between the dates (aside from texts) to do build our relationship, but keeping it mind that this is still at a delicate stage.
