I reached out to my ex because I needed closure from the relationship. He said he missed me very much but never responded. We were talking politely and asking how we both were doing. He also asked when I was moving to Chicago (He wanted me to move to Chicago otherwise the relationship would end. It ended anyway.) After I didn't respond to a text from him he texted again a couple hours later saying, "In case you are wondering I miss you very much and I don't like the note we ended on. I feel guilty about the last message too cuz I know I never made you happy. And I am very sorry about that. You deserve much more." After I said that it would be better to talk about this kind of thing in person, he never responded. What did this all mean?
Should I follow up with him? Or would that make me look crazy and desperate?
