Why does he want to keep in touch?

We have been friends & only friends for 10 years but for the last 4months our friendship has been more consistent, via text, Facebooking, emailing & the occasional night out. But now I'm quite heartbroken he's seeing someone...quite sudden to me! He was tagged in a photo with a girl & they looked like a proper couple. I told him via text I wouldn't contact him again as I didn't realize he now had a partner? At first he said he wasn't sure what pic I meant or how recent it was. To cut it short, he did own up to...he is now sort of seeing someone & didn't think I would be upset by it as he thought we were just mates! I then did reveal my true feelings to him . He said please don't fall out with me & pls stay intouch I'd hate it if we were to loose all contact :(. Lol why has he done this? Guys please explain?
