<human>: I (American) recently moved to Germany and started talking to this German guy I met online at the beginning of the year. We have a lot in common (languages, education, interests, etc). He lives 4 hours away and I live in his hometown. After a month of writing each other everyday he came to visit and we had our first date. We met for drinks and talked for almost 4 hours. We had a good time and finished with a nice kiss.

Another month passed and we were still writing each other everyday. He offered to come visit him, which I accepted. Except, when I arrived he was extremely quiet and shy. He didn't speak that much and when I asked him questions I would get short answers with no questions from him in return. He was still nice to me and we even cooked together and walked around the city. I'm really attracted to him and we slept together a few times. He just didn't talk to me very much and I got the feeling he wasn't interested. 

After that weekend, the communication started winding down. I called him a couple days after I returned home and told him how I felt (that he didn't seem interested). He assured me that he really was but even afterwards, we slowly stopped talking. Is this because of cultural differences or was he just not that into me?

Provide a brief overview of the text.
