I am pretty sure I am not invited to a church friends wedding that Ive known for years because she deleted me on Facebook and I had a falling out with her sister where she yelled at me for wanting to crash this other mutual friends wedding years ago. Would it be rude to just ask why Im not invited to make sure it wasn't because of the thing with her sister and me wanting to crash this persons wedding years ago? I asked her why she deleted me on Facebook and she said shes only keeping people she talks to regularly, this was several months before she got engaged.
