Please help!

So I am 14 and there's this guy that I met few weeks ago but I'll never see him again because we live way to far away... He's depressed and so am I but I don't cut. While I was with him it was amazing and he was the first person I ever opened up to, and had my first kiss with him. But he doesn't like me back at all. I have no idea what to do. Since he left I feel a lot worse but he told me a few days ago he has a girlfriend and didn't text me since. I don't want to be the stalker and annoying creep that texts him all the time but I don't want to lose him, and I don't know how to get over him.
