I met someone on a online dating site a couple of weeks ago. The first meeting went fine. We live about 3 hours apart and met about halfway. At the end of the date he asked if we could meet again the following weekend. We met again pretty close to the same place this Saturday. We had a good time and I thought it went pretty well. There were a few awkward moments but nothing out of the ordinary. He seemed truly interested in me until he left, and then it just seemed very obvious to me that the interest had declined. He said something like "maybe we can do it again sometime", but no plan or suggestion for a specific meeting. And of course, he hasn't called since. I have messaged him with generic stuff and he did answer me but that is it. I have been trying to remember something I might have done or said to offend him but obviously I don't know what it was.

I have one friend telling me to keep in touch with him and maybe even invite him to come to my town. Then I have another friend telling me to back off and let him come to me. I know from previous situations like this that if a guy appears to no longer be interested, he really is not interested, so I'm inclined to back off. But I also would like to know what changed. Maybe ask him at some point? I just hate the games that go along with the dating world! Any thoughts?
