My Ex Reached Out After Years of No Contact, What Was the Point?

A few years ago he and I broke up because our relationship started to go down the drain due to him not filling out any job applications while being unemployed. I never really cared about the money, but I watched how his mental health was on the decline the longer he stayed unemployed. Also, him not even trying made me feel like he didn't care about the future we'd discussed together. One night he finally broke and told me he wanted to end it. We talked it out and I thought he was reconsidering (he said he needed time to think), but he just disappeared. For the most part, I heard nothing from him for almost 2 whole years. Last summer, he messages me and apologizes for his mental health getting in the way, saying I deserved better from him and wishing me well in the future. He again disappears. A week or so ago, he reaches out telling me about how he got a nice cushy job near where we used to live. I tell him we should play a game together that we used to like a lot and he says that he doesn't want to get addicted to it again, but if he feels like he can play it without doing so he's down. After that he sends me a big family update, and then a meme, asks me a question about if he should get an outfit and we talk a little. But then the last couple of days he just kinda falls off. I guess I'm just a little confused. Him reaching out like this shook me up when I thought I was over him. I don't understand what the point of any of this is.
