*Possible spoilers* I might have misunderstood it, I don't get why there's a lot of people thinking that they never met again. While it wasn't SHOWN, it became quite obvious if you paid attention to the details in the last few pages. And that's one of the best things about this story, yeah it's sad that he had to be alone for so long, but it's awesome that he became that which she loved (not expecting her to notice him doing it) and it was then that she appeared once more. There are no guarantees that they will become a couple, or that they're even still single, but the fact that they still get to meet, it's something that I find very "heart healing"... if that makes sense :D
