Have you ever been....?

betrayed by a friend you trusted? Please share how you dealt with it? A friend of mine asked me to be her bridesmaid and because I didn't show up to one of her wedding frundraisings she decided to stop taking my calls or replying to my messages. I gave her $100 as a gesture for not making it to her fundraising and even bought my own bridesmaid dress and do I get ignored. She still hasn't called and the wedding is in 2 weeks.
