Is he losing interest in me ???? Help !!!?

2 weeks ago i met jason. He was so fun, we went dating, gay baring, cinemas etc together , holding hands going walking ... it felt amazing, it felt like my old bd relationship was blown out of my head and replaced by him ... hes gone to spain until early august, when he first went there he couldnt stop faceb ooking me etc and it felt great, 2 days ago it stopped..... hes online but doesnt say anything until i say something ... its weird ... honestly, i realli like the guy and im not happy with this ... hes going offline then without saying anything ... its heartbreaking cos i feel hes losing interest, i asked him '' do u not like me anymore???'' and he said '' i do, im just busy'' ... i really dont know wot to maje of this ... any1 help ???
