My wedding is being held in a different state than where I currently live and work, and it's about a 6 hour drive. A co-worker has started to plan a small shower for me, with about 8 of my closest female co-workers. If my wedding was local, I might have planned to invite most if not all of these co-workers. Is it rude to go along with the shower and not invite these women to the wedding? I don't want them to feel obligated to buy a wedding gift if they receive an invite, and I certainly don't expect them to drive 6 hours to attend the wedding. Will they expect an invitation?
