Got a message from my ex. What does he want?

I gave this a lot of thought so I hope you hear it out.The reason I ask to meet in public wasn't to get back together It was because I didn't want things to escalate. I figured being in public would help keep voices and tempers down. I wanted to give closure and set things up to be civil and even friendly down the road. You were never anything less than my best friend. Your response was very hurtful and you said many things that can't be taken back. I was so suprised it was like I was speaking with stranger or someone I didn't recognize at all. This in response to wanting to meet after the sudden and unexpected ending over the phone. Instead of bringing about closure and tieing up lose ends it called in to question my feelings and asserted some pretty terrible things about me. This paired with things I heard from mutal friends and the ending on the phone hurt. I wanted to talk it out but it felt like you deliberately burnt down that bridge. I knkw tensions were high, and I hurt you in ways I wasn't even aware and for that I am sorry. That being said, I never expected things to get so acidic between two people who at the heart of things cared so deeply about one another. I really did/do love you despite what you may believe. I wanted to wait until we both had time to heal before replying because I was afraid of escalating things further. Sometimes when things get heated you need to walk away and calm down before a real conversation can be had. You taught me that.

I’m not sure what the purpose of his message was? We broke up back in July and haven’t heard from him since. I broke up with him because he was an awful boyfriend but what does this message mean??

Thank you
