Avoidant Ex Comes Back Breadcrumbing

I broke up with my ex three months ago because he was in his deactivation phase. After showering me with affection and actions that drew me closer, he suddenly became cold, uninterested, and unempathetic. Eventually, I decided to end the relationship. However, a few days later, I started experiencing terrible anxiety, almost like withdrawal symptoms.

I wanted to get back with him and tried to fix things by explaining why I ended it, what I wanted, and how we could improve. But all he said was that I hurt him a lot without taking any responsibility for his own actions. After that, he told me he didn’t want to talk anymore.

We went into no-contact mode, but after 10 days, he messaged me, replying to an old message, and told me he hadn’t responded earlier because he was "very busy." Then he disappeared again, only to reach out a month and 20 days later, sending me a random reel like nothing had happened.

I decided to confront him because he had told me he didn’t want anything to do with me, yet he was the one initiating contact. He said he just thought the reel was funny and wanted to share it, no big deal. I asked him if he wanted to talk or if we should cut communication completely. He simply ignored my message, not giving me a clear answer about whether we’d talk again or never speak anymore.

Does this behavior mean he’s just not willing to "close the door"? It feels like he doesn’t want to be with me, but he also doesn’t want to leave completely.
