Bummed out. Why didn't he pick me?

This guy I really like made out with me and acted really into me and said he wanted to hang out so he didn't want to go any further, and I really got my hopes up. But then he backed off and didn't really do anything and it's been a few weeks and I heard he is trying to get some other girl to be his girlfriend. What the hell? Why would you act interested in me..did you meet someone else like 5 minutes later? :[ I'm sad... I like him so much.
