I care, I bloody care but I know it just doesn't matter.
Human will always go for something/someone better if given chance. After all, why not? We are an opportunistic creature, we won't let a chance slip away. I did the same as well, so I can't really hold grudge when others did the same to me.
Still, it hurts a little bit to realize that u matter less to others.
Ah well, we change. Nothing stays the same.
Be happy that the paths intersect even for awhile.
Time to move on.
