I am sorry for your pain. I have also had the experience of having spent fairly little time with someone, yet, being really drawn to them, for some reason. It happens. Sometimes, we just click with people, I guess.

Personally, I am a you-only-live-once kind of guy. I have been in a similar situation and what I decided to do was to reach out. Won't get into it here, but it was the right thing to do for me at the time.

Maybe you could just send a not-over-the-top email, seeing if he would ever be interested in maybe having coffee or something. Something low-key. If he declines, well, you can go on knowing that it was not for lack of trying.

Good luck, whatever you do!!!!
