My dumper played me again

My ex fiance and I were together for 5 years in a long-distance relationship. He was genuinely a great partner. We had normal fights but nothing that made me think we were going to end. Then 3 months ago he suddenly broke up with me saying he didn’t want to continue and didn’t think we could live together. He became extremely avoidant and I begged him to reconsider while he left me crying. Eventually I accepted it, blocked him, stopped contacting him and started trying to move on.

About 1–1.5 months later he started emailing me again. It began with practical things like helping me with my taxes but then turned into random messages, interview help, asking if I was okay, saying he was restless and worried about me, and telling me he was genuinely happy seeing me “flourish.” After seeing all these emails I eventually unblocked him on WhatsApp and messaged him saying it was fine and I would deal with everything on my own. That led to a conversation between us where he continued saying things like he regrets breaking up with me every single day and he isn’t doing well career wise and marrying me would be like he is bringing me down with him which he didn’t want. And he isn’t doing well in a shit hole that he has created for himself and that he also discuss it with his friends that he pushed me away and now he can’t cope up with it.

At one point yesterday when he got to know im dealing with an illness he suddenly said, “What if I came back to your country and we start it over?” I asked, “With me?” and he said yes. I asked why and told him to just tell me the truth. He said he had to go and would talk to me later. I then later bluntly asked him why he wanted to go and whether he really wanted to fix things with me. He saw the message and basically disappeared. I called him and asked him to answer me because he had seen it, and he just said, “I shouldn’t have disturbed you. You’re doing great in life. Good luck,” and pushed me away again.

I’m completely confused and devastated. He spent weeks reopening a door I had finally closed, telling me he regrets leaving me every day and thinks about fixing things, then told me he wanted to come back and start over with me. But the moment I asked him what he actually meant, he ran away and told me he shouldn’t have disturbed me.
