I've been with my FI for 4 years and have only met his childhood friends a few times. Even though they really haven't kept in touch much throughout the years he decided to ask them to be in our wedding since they were very close growing up (3 of the 11 groomsmen). Should their wives be invited to my shower even though they don't know me? I don't want them to feel obligated to come but I also don't want to offend anyone by not inviting them. Help!
