long distance dating

This is not only long distance dating but someone I met on vacation in Mexico and I am a U.S. citizen. I realize for something like this to work is a long shot. However, I think that I may have even blown the friendship. I am getting overly invested and emotional which I realize is not healthy.
Long story short. I went to Mexico to study Spanish. I went with my host family's daughter to Acupulco one weekend. I met someone who seemed like a supernice guy. I am 32- he is 26- said age difference did not bother him. His story was that a few months ago he was engaged and caught his fiancee with another guy. They had to call off the wedding, he asked for the ring back and was very depressed. He said he feels much better now. He went on and on how he was so happy to have met me and felt a connection. Nothing physical happenned that weekend. However, the following weekend, he came to visit me where my host family was staying. He stayed at a hotel and I spent some time with him there. We started to have sex but I felt like it was too soon and started to not be into it. He noticed and stopped. I didn't stay over night but he came and brought me to the bus the next day. I was leaving to go back to the states and had to take the bus to the airport. I returned to the states late 1/21/06. He got all my info and called me the next day. He said he was in the midst of an important work project and would be quite busy. However, he stayed in contact for the next few weeks pretty regularly. I started to feel frustrated on Valentine's day when I didn't hear from him until the end of the day. I expressed that I was kind of upset. He was supportive and said he had been busy but would try to email more. I then got one email from him after that. Two weeks went by and I never heard from him. I was trying to be strong and not contact him. However, I gave in today. I called him and he sounded quite distant. When we were first exchanging emails, he kept talking about planning a trip to visit me btu he wasn't sure when. This time he was even more vague about it and sounded quite distant. I shouldn't have called him because I was quite emotional. I had to use a pay phone because my cell has no international service so I was on the street. I thought I was going to cry so I didn't answer him a few times when he said something. He kept asking me what was wrong and did sound concerned. I started to cry and felt mortified so I said I would talk to him later. I ended up kind of hanging up on him. It wasn't really to tell him off but just because I was embarrassed about crying. I emailed to apologize and have gotten no response. Am I being a crazy woman- should I apologize again for hanging up or leave it alone. He is Mexican and in his culture this may be even a bigger insult. I don't know if I will never hear from him ever again now. Just need feedback and some advice on what to do or not to do now.
