I'm planning a shower for my cousin (who was MoH in my wedding and we grew up like sisters) with my mom and her mom. Its going to be a surprise and I'm in charge of invites. My aunt and his mom have given me lists and addresses, my issue is with her friends. She's not married so its not like i have her wedding guest list like she had mine when planning my bridal shower. How do I know who to invite and how to get their addresses? I can contact some on Facebook and her BF is no help
