So I have a bridesmaid (I've know for 20 years) that has been promising me for the past 6 months that she would absolutely be at my bridal shower, as well as my bachelorette party, and be in town early enough for a family and friend BBQ that we are having, and yet when the bridal shower came and went, no bridesmaid, no call, no text and no email. And then, this week, the week before my wedding, she emails me to tell me that she won't be at my bachelorette party or the BBQ and that she will be driving over on the day of the rehearsal instead. So this whole time she promised me she would be there for me and keeps telling me to let her know if I need anything from her, or if she can help in any way, and yet, when all I ask of her is to be there with me during my last few days of being single, she bails with just really bad excuses. And now that she isn't coming into town until the day of the rehearsal, I'm afraid that with her track record that she'll miss it. So my final decision has come down to that if she misses the rehearsal too, that I'm going to have to cut her from my wedding party. Is this too harsh?
