Guys, Does this behavior mean something?

Dated a guy for 4 months and decided to part ways since I wanted a serious relationship and he didn’t. It was a friendly breakup. We still follow each other on Instagram, and sometimes he likes my stories or reacts to them, or asks me where is the picture from. Why would a guy maintain such behavior? He isn’t making any effort to make any further conversation, and it was clear when we ended things that I had more feelings then him.
