Reunited with boss's son after years

I recently got back in touch randomly with my old bosses’ son from college on facebook and he asked me to a wedding of a good friend of his. I remember how he used to look at me when he would see me at the office (he didn’t work there) and I didn’t mind bc I kind of liked him, too. My sister still works there and everytime she sees him he inquired about me, apparently. He is a doctor and right now he is out of town doing his residency, but he calls me a couple of times a week. For almost two weeks he didn’t call me, and that sort of upset me so I emailed him to ask what was going on. He called me that day and apologized profusely, once on a voice message and another time in a conversation we had. Both times, however he kept on saying that he wanted to be friends. Is it just me or is all this just strange? I stopped dating for awhile to avoid this kind of drama. Initially I did just want to be friends w him, but when you are asked to a wedding and a rehearsal dinner and this guy is calling you, what is a girl supposed to think? Now I don’t want to be friends. I want us to date like normal people. I could see why it would be difficult since he lives a few hours away and he is working 90 hours a week, but I still want that. Please help. My mom is deceased and I don’t really have anyone reliable to ask advice. My girl friends, of course tell me what I want to hear.
