Last time I felt like you're describing, I had found a best friend. We were intimate for a bit, but long term we were romantically incompatible. He moved away, but 10 years later we are still very close. So close, in fact, that it raised a few eyebrows at my wedding because we forget to give each other personal space lol. Lucky for me, my wife adores him so it doesn't cause problems my marriage.
All that was to say don't take that strong connection for granted because you never know where it might lead. Things could go to a perfect but unexpected place after the initial rush wears off.
