Just two week's ago I introduced two of my friends to each other. One of them has been my friend for about 10 years and the other my friend for about a year. As soon as I introduced them they 'hit it off' and started hanging out together and started saying that their 'twinsies' and my best friend is doing things with the other friend that she won't even do with me (Like hang out outside of the school or go to the mall for a girls day). and If I have to say, I feel like I'm jealous....I think its Jealousy, but I don't know why I'm jealous of a friend ship...I'm not even sure it is even possible. Does this mean that I like my best friend more then I actually do...or is this normal to feel jealous when this happens?
