So I'm a little neurotic and even though we're still a week out from my RSVP deadline, I started following up with people because I hadn't gotten responses from nearly half of my guests. For reference, the wedding is June 10, RSVP by May 20, invitations were sent in early April. I messaged a friend I haven't seen in many years, but our friend group has been in touch over the years on facebook. I basically just said I was trying to get an idea from people who hadn't responded yet to see if they knew yet if they were planning to come or not. She read it but never responded. I jokingly said that I could see that she had seen my message. Waited a day, then messaged again just saying hi. No response. I'm a little concerned so I sent one more message today asking if she's okay and still haven't heard back. I wouldn't be angry or upset at all if she's not able to make it, but it's a little irksome and hurtful that she won't even reply. Was it rude of me to follow up before the deadline?
