Wow – I am really impressed with what you wrote. It is AMAZING, honest and feels to me like you managed to get everything off your chest. You should be proud. Heck, I may bookmark this to use excerpts in the future. ha ha

As for your other questions (“what does it mean?”, etc.), it’s impossible to get the answers to that from anyone on here. We are not him and we don’t know what was/is going through his mind. The only way you could find out is by asking him … but in all honesty, I don’t know why you’d want to. This is finished. You should have no reason to reach out again and it’s time to move on. Use your email as closure and continue forward. Leave him be to reflect on the karma he creates for himself.
