Is my friend playing me?

I have a friend who I catch up with once a year. We were previously closer. I rarely make an effort because he makes hardly any effort.
I contact him on social media and he responds and says it’s good to hear from me and we should catch up. He says sometimes he doesn’t reply as he is busy.

I said if he doesn’t want to be my friend then he can say so or just not respond. He said we are good friends. And he is old enough not to play games.
How can I get a friendship going the way it was before? Is he even worth caring about?
