In the end it's your day and you should have the people that you want in your wedding. I actually had to recently tell a friend that she was not going to be in my wedding and i just polity said actually i'm only having blah blah blah (that i've been close with for years, she was someone who i met about 2 years ago) I'm not sure if i hurt her felling but she said she understood. You are going to have tons of bridal party pictures and you want those to represent the people you wanted in your wedding.
