Here is the situation. I use to write messages back and forth with a friend's mom on facebook after I met her at a close friend's wedding that I was a bridesmaid in. So probably around 2 years ago she said, "promise me that someday when you and 'Bob' get married that you will invite me to your wedding"...and I said yes I will. We are now getting married in a little over 3 months. I am totally fine with sending her an invitation but I haven't talked to her for a long time. I did see her at a friend's child's birthday party in December but that was the last time we spoke. Also, I am planning on inviting her daughter (my friend) to the wedding. Should I send her an invitation since I promised to a couple years ago? Thanks!
