What does it mean when my ex suddenly liked a story that has pictures of me? Does he miss me?

He liked a story thats a collage. Every 6 pictures of them have me. We have been broken up for few months. He has treated me badly. I am not sure he's trying to tell something pr giving a hint that he misses me?
