Is it normal not to get a response after sending an email like this?

[Anonymous]

My coworker still has two more weeks left at this company. He's a contractor so he doesn't use company email. I sent him this yesterday,"
"Hi ______,
I enjoyed working with you all these years so it's sad to see you go. I know I haven't worked with you much in recent years, but you were one of the first people I met at LS when I started as a case manager in 2008. Thanks for being a support during some of my more challenging cases way back in the day. I wish you the best and good luck. Feel free to keep in touch.

• He def knew I had a crush on him years ago, we used to flirt without it going anywhere (not single). I was laid off for years and came back. We had a nice long catch up conversation but with our schedules rarely lining and with covid reducing his client base, I haven't seen him in person since Dec 2019 (when I almost crashed into him as he rushed out, late for something and he thanked me for processing his plans) With our long work history it seems cold not respond at all, no? Or is to be expected because I haven't seen him in so long?

Well... not seeing each other for so long may dwindle whatever feelings he may have had for you or not, but I think speaking directly to him about it and seeing where it goes is the better option if you do want to pursue a relationship with him. Otherwise, it's just pointless speculation.

Tbh your email didn't really require any sort of response.

I find it weird you expected him to respond.

He just replied
"Greetings.
It was so lovely to hear from you and thanks for the kind words. I remember meeting you and our early conversations as I was impressed with your intelligence and understanding of the work we do. I am working a lot for [agency 1] along with [agency 2], [agency 3], [agency 4], and [agency 5] so our paths may (hopefully) cross again.
Best wishes,
[Coworker]"

So all is well. His reply was better than anything I ever expected. But considering I barely saw him at the same agency and now he apparently works for every agency BUT mine, I don't expect us to cross paths again but it's all good.
