In some ways yes, in some ways no. It only means they are insecure about themselves, a true friend should support your accomplishments, not make you feel guilty. Just tell him or her what they do great and that will make them realize they are no lower then any body else. never ever change yourself to be worse then she is.
Date the guy your best friend likes.
she is jealous of her or him
Why is this a problem for you? Is your cousin a bad person? Is your friend a bad person? If the problem isn't a safety issue then you should wish your cousin and best friend a long and happy relationship. You may want to ask yourself if you're just jealous of the relationship they share.
Your friend should not be jealous enough to endanger your friendship. But you can let him/her beat you at something to help cool down the friendship.
maybe he/she is jealous of what you have
date her BEST friend.
Beck did not get jealous because Jade liked his best friend Moose. They were all friends and did not see it that way.
