I don't think you can say 'no need for false pleasantries' and then say 'enjoy your wedding', when you clearly don't like her!
I find it hard to put myself in the place of someone who feels they ought to be invited to things. I often wish I was, and feel sad and disappointed when I'm not, but I always assume that it's down to me - I'm not a close enough friend, not interesting enough, not easy enough to be with, whatever, and hope that I'll be able to change it. I know that's low self-esteem talking, but I'm always still surprised when people are so sure of their places in others' lives that they deserve invitations, and that someone else is being a bitch/cow/bridezilla etc when they don't invite them, and don't grovel about it. When I wasn't invited to a friend's recent wedding, and hoped I might be - I realised we weren't close enough. I was a bit hurt and sad, as I thought we'd been closer than that, and closer than some who had gone, but clearly not. She does have zillions of friends from different walks of life. I sent a card and wished her well, and she thanked me - no mention of why I wasn't invited, and I woudln't have expected there to be - why should she apologise or anything for something that was clearly the right decision for her? I doubt she even realised I felt hurt, not because she is a bitch, but because it was just a normal thing for her to have invited those who she was closest to, and she didn't see me in that category, or realise that I thought I was closer. And it could be the same with the OP's friend. People have very different views on how close someone is in their life, and she might have thought that the OP quite ordinarily accepted the fact that she wasn't close and wasn't invited, and genuinely thought she was wishing her well - see you on the other side is just the sort of thing you might say to someone you liked, but weren't super-close to.
If you dislike her enough that this is the end of the friendship anyway, then it doesn't sound much like you'd actually want to be there for her, so I guess in some ways it doesn't really matter. If you do honestly like her and want to be closer in her life, why not wish her well, be interested in the wedding and photos, and then work on the friendship longer term and see if it's going anywhere?
It doesn't mean it doesn't hurt, hugely, to find out that you aren't as important in someone's life as you thought. But it doesn't make that person heartless or stone cold or bridezilla for not realising it. She might have equivalent relationships with lots of people, and see them in a different light, more like acquantainces that she sees every few months. Even if they invited her to events, it doesn't mean that she sees them as particularly close in the same way.
Be sad, be disappointed, but try not to be bitter, I think, if you can.
