I had the same situation with two of my bridesmaids. I got engaged a couple of years ago and back then they were really great friends, but as time went on we grew further apart! when it was time to do things with the bridesmaids, I just didn't contact them. I wasn't invited to one of their weddings and wasn't told about it either! We didn't have a fight, we just grew apart and that's ok! You dont want to have someone in your wedding party that isn't a special part of your life anymore!! I hope that helps
