<human>: Summarize the given text in a few sentences.

Back story, this guy and I at some point had feelings for each other but it didn't work out, but it seemed like we were cool after. We met at work but we no longer work there. It's been a while since we talked. Now we're both moving on to different career paths out of the city to different parts of the world. We were messaging back and forth and my last message was about wishing him well in all that he does. I do/did have feelings for him but I know now there is no chance of it happening. 

 I don't expect to probably see him ever again and so I wished him good luck with everything and he hasn't responded or acknowledged it. Been about 5 days. He has been online so it's not like he was busy. I wonder if he hates me?
<bot>: Guy isn't answering or acknowledged my "wish you all the best" message. I would at least expect him to say it back even if he doesn't mean it. What does this mean?
