Question about ex

Sa

so my ex and I broke up a few months ago; he dumped me completely out of the blue and said it was because we didn’t see each other enough, but I never really believed him and I thought there was another reason. anyway, we’ve been on good terms recently — we don’t talk much, but when we do, it’s simple small talk. I miss him more than anything. I was in love with him and it was the happiest I had ever been, and I miss him every single day. I’m pretty sure he’s completely moved on though. a bout 2 weeks ago, he messaged me and told me someone had said to him that he’s changed for the worse over the past few months, and he was wondering what I loved about him when we were together so he could figure out how to become a better person. I didn’t really see this as anything, but as soon as I told my best friend, he said it was a lot more important than I think it is, and that it means he wants to become the person I loved again because he misses us being together. is my friend right, or was my ex just asking me that question as a friend?
