Am I wrong for being upset?

My ex came back in my life and told me he still feels the same way about me. He told me that he still see me as part of his future & how it’s hard for any of that to change. He stated nothing has changed, and he still feels the same way he always had. I simply asked him why is he telling me of this while doing nothing about it. He’s not fighting for me like I did for him. I fought hard for him & our relationship and in the end he pushed me away and disregarded me. He’s not trying or putting in effort to make me FEEL wanted. He’s doing nothing. His response to what I said was, “well what is there to do about it? One of the reasons why I’m not doing anything is because I don’t want to interrupt the peace where you’re at”

This simply pissed me off because why tell me all of these things, and do absolutely nothing about it? Why tell me your feelings for no reason at all? What is he getting out of this? It’s like saying, “I want to be with you but I don’t want to do anything about it.” It instantly annoyed me because of all the excuses he makes. The relationship ended because of him. The lies, the cheating, the excuses, the treating me badly etc etc.

Am I wrong for being upset?? Why come back into my life to tell me how you feel, but you’re willing to do nothing about it???
