How can guys jump from girl to girl so fast?

Anonymous
I was talking to a guy for a couple of months and we hung out a couple of times. Since it's summer, we can't see each other because of distance, but he told me he wanted me to keep in touch. This was two weeks ago. Yesterday, he got a girlfriend. Did I mean nothing to him? Was I just some random girl to hook up with? I really thought it was going somewhere, but apparently he didn't see it that way. Guys, how can you just move from girl to girl so fast and forget about us once you've moved onto the next one?

I guess it just hurts because I'm a bit shy and never had a guy interested in me before. He was one of the nicest guys I had met in a long time and was really patient with me. Maybe I just saw it for more that what it was :(
