Hi- I'm standing up in a friend's wedding this September. I attended one of her bridal showers last month. I received an invitation to a second shower which was to be held the same time my family was visiting/staying with me from out of town. I called the groom's sister (shower host) and left a message that I would not be able to attend and explained my reason. The shower was yesterday and my friend sent me a text saying "are you okay?" I responded "yes, I'm fine. I left a message that I couldn't make it since my family was staying with me. Did you receive my message?" and no response. Now, I'm worried that she's upset. I probably should've called to tell her as well as the host but I didn't think of it at the time. How horrible is this? Should I reach out and apologize for not going?
