I'm not really sure where to put this, but I figured the etiquette board was as good as any.
I was friends with this girl for years, since like 7th grade. When I got engaged, I wanted her to be a BM. I asked her, she said yes, things were good. This was VERY early in my planning process. Then, we did not see each other for a few months. Around the time that things were really getting started, I asked her if she still wanted to be a bridesmaid and she told me she didn't think she could because of finances and other reasons. I told her I totally understood.
Flash forward to sending out invites/save the dates. I needed her address (I grew up with her so I just knew where her house was, not the physical address). I texted her and she texted me back with her address. She was sent save the dates and an invitation.
Then, nothing. Never got her reply card back. I texted her to see if she was coming, no response. I called her. No answer. Left a message and never heard back. I then went to check Facebook to see if something else was going on, and she is gone from FB too. I am worried about my friend but don't really know what to do. We don't live in the same town anymore so I can't really just drop by. Was it something I did? Why has she disappeared? It's weird and I am worried about her and don't know what else I can do further.
