My fiancé and I are having a very small wedding with only immediate family (40 guests) . My mom called me today to say that my step-grandmother was hurt that I didn't invite her. I've known her since I was a child but I have never been particularly close with my step-grandmother, and my stepdad passed away 5 years ago. We have kept in touch on Facebook occasionally, and she sent a gift when my son was born. I didn't invite to the wedding because we are really only having close family and I didn't want to make her feel uncomfortable or feel obligated to send a gift.
My brother's birthday is today and while step-grandma was at my mom's visiting him, she made a comment that my wedding is soon and that she was hurt that she wasn't invited. My mom told her the invite probably got lost in the mail. I feel really bad now because it was never my intention to hurt her feelings. What should I do? Is it too late to send her an invitation? Our wedding is in 3 weeks.
