It is completely a loss.
When he said, “We never know what the future holds,” that is often a dead giveaway that he doesn’t truly see you in his future.
A man who does see a woman in his future would not just leave things to chance.
He wants to focus on his new business.
This means that he is most likely not going to make any room for you in his life, save a few platonic exchanges here and there.
Continuing to look at this guy as a long-term romantic prospect would be a waste of your precious time.
