I was invited to go on vacation with my friends.They were going for a friend's wedding whom I don't know. A few months before we were going, they said that I was not invited to the wedding so it would not be a good idea to go on the vacation. Do you think that's a valid reason why I should not go? FYI: There are six girls total including me but I don't get along with two of the girls. What should I do?
