Confusing guyyyy... desperate need of help?

Ok so theres this guy that I really talked with a lot on msn, and as soon as i got my fone he asked me my number several times so I gave it to him. He used to go to my school but he switched schools so yeah. So he would always call n text me like literally everyday. I never called because I knew he will call. So yeh we met up and yeh got just a bit intimate like a kiss and watching a movie together in his basment. The dai after we met up he continued calling and texting me and the last thing he sed to me was call me back but I didnt cuz whenever he said that he would just call back himself. but sudddenly for whole wek he didnt call or text me and i found out that he's tellin this girl how I'm so annoying and how i always texed him. Which is a liee, i never did that. And now i hear he has a girlfriend. He msged this girl on fb n said call me and she sed you already have a gf and he was like f**** what my girlfriend thinks. Like do you think he msged my friend cuz he wants to know about me? Cuz like i really like this dude but he goes to a diff school to. I just don;t beleive how he got a gf in just a wek. Is it to make me jealous? What do you think? Is there atleast some feelings in his heart for me? He always complimented me I don't know why he's doing this? Help
