I suspect reading this back I already know the answer, but would be interested in your opinions.
A work colleague was getting married, I knew her quite well (had also covered her mat leave). She would ask me to meet every day for lunch, which I was happy to do, and she would spend the time talking about all her wedding 'stuff'. This went on for several months. One day she brought the sample invitations in and showed me. That afternoon she emailed me to say that the wedding was only 'close family and friends' so unfortunately there was no room for me to be invited.
I guess (to my shame) I must have said something implying I thought she would invite me, which triggered the email. She also brought the pictures in afterwards and showed them to me. It was held in a castle with about 100 guests.
AIBU to be a bit miffed?
