If she let me kiss her and then she kissed me goodbye too, she likes me right?

I have gone on three dates with this girl and the other day we had a great first kiss and then when I went home she hugged me and kissed me goodbye. She's on Spring Break now several states away for a week. I don't want to let the momentum subside, but I also don't want to bug her with texts. The problem is she shows she likes me physically, but she doesn't text me randomly or call me randomly, the only time we talk is in person and to setup our dates. Like when she was on the plane on Thursday I texted her, "hope you have a good flight" and then she sent back, Thanks! Have a nice Spring Break! I took that as we'll talk when I get back, not an invitation to text her while she is away. I don't want to act like the first kiss was a huge deal to me and appear clingy, but I do want her to know that I really like her. God this is confusing.
