Does this french guy has a thing for me?

I met this french guy at the bus stop. I am studying french philology, and he came to my country like Erasmus student. He started text me, we were having very good, funny conversations as I knew him somehow for a long time. We were talking about relationship and he said he has a girlfriend but she trust him. He asked me out to go to karaoke. I could not go, we still communicated, he liked every my photo. Then he came back to France. Now he never likes my photos, when I write to him he is so happy but do not continue a long messaging. Why? He used to call me ma poule, ma pote.
