What does it mean when an ex does this?

My ex broke up with me over a year ago and still doesn’t leave me alone. Even if blocked or I don’t respond to his messages for months. He broke up with me bc he got cold feet and thought I got attached too fast but we had a wonderful time and traveled together a lot. Not to say there weren’t down times but we dated for almost a whole year. A couple times he sent a text about getting back together but then he acts not serious with actions.
