Why is he liking and unliking my posts?

I stopped talking to someone I love two months ago. It was complicated, we couldn’t be together because of our backgrounds and he didn’t want to bring me into the chaos of his so i stopped talking to him, no animosity. I noticed he was liking a lot of depressing things like “I miss you” blah blah. He recently liked one of my posts then 20 mins later he unliked it. I’m confused why he did that. Is he Trying to get my attention?
