I had a friend like that (who's not invited now). But if she doesn't want to come, it's ok, at least you know where you stand to that person. It's kinda harsh to say. But if she can't come, that's fine. But why add insult to injury? What satisfaction would she get? None, like others said, she's jealous and trying to come to terms. My advice, accept her invitation retraction, and do not mention the wedding to her. Chances are, if you mention it to her, this is all she'll do. My maid of honor was like that. She was always telling me how rediculous it was for me to spend all that money. (But she was planning for me and a bunch of her friends to go an hour away for 2 nights to a casino hotel! On our own tab!!) Let her go on with life, but know that chances are, this is nature's way of showing her true feelings.
