Do you think he is honest?

Before few months i met a foreigner guy in my country. So he will stay here just for few months and then leave. The things is he was so honest with me, nothing mysterious. He used to open up to me about everything in his life. Pay for my dinner, cook for me. The sex was amazing, the chemistry was so good! We both felt so comfortable. We used to hang out every day!
Out of the blue, he just stopped talking to me. I asked him what’s wrong? What’s the reason?
He said he doesn’t want to get attached because he knows he is not staying in my country forever. What do you think?
