Is my ex just being friendly?

Ex and I saw each other after 10 years. During the time we’re apart, I also immigrated to another country. When we met again, he has been sweeter this time, very caring and has been telling me he’s changed. At one point, he also called me just to play my favourite song on the guitar. Even gave me a gift and stayed with me before my flight. When I arrived to my now home country, he just said, the time went by so fast and after that he basically didn’t talk to me again. Until last night. He greeted me Merry Christmas. Is he just being friendly? Or am I still special to him?
