Young love? GO AWAY!

So I've been talking to a great guy friend a lot lately and have been feeling things for him. We met up in town and I had a great time, I was flirting with him. That week he has been telling me that I looked great and didn't need to diet etc. Just the perfect guy, right? Until we went to the cinema last night and I found out he had been dating a good friend of mine for the past few days. NO ONE TELLS ME ANYTHING ANY MORE!
