KC, great job in not replying to him! I know that had to be tough but it was the right thing to do. I agree with what everyone else told you, I read it as him explaining to you why you two are done and that he is moving on and happy. I think he's trying to convince himself more than you. His last question "Do you want me to look back? What do we have to offer each other?" sounds rhetorical to me. I don't think he was genuinely asking you because he wanted a response, but rather was just saying "wouldn't you agree that we have nothing to offer each other?" Sometimes the WAS will send out a stream-of-conscience message like that. It doesn't mean anything, his mind is all over the place and he just landed on that briefly and decided to send it out to temp check you. Literally ANY response whether positive or negative would have cemented your spot as Plan B. No response is perfect, because now he's really confused. Now he feels Plan B slipping away, and what if Plan A isn't so great after all? Which it isn't, because if it was then he wouldn't have sent that in the first place.
