Do remember that some kids more than others feel the need to push away from their parents during their teens. It might be that she does recognise the sacrifices you've made to the extent that it makes her uncomfortable because she can never repay you, and this is just her clumsy 16 year old way of removing herself from the situation.
It might just be easier for her to accept big gifts from her dad because the money is a drop in the ocean to him, so not necessarily a sacrifice in the way it would be for you, and she might feel that the balance is more equal in that he 'owes' her for not having been the resident parent (not meaning to make any parents in similar situations feel bad - the OP does say he's a selfish bastard). Whereas taking more from you and more of your time just adds to everything she's well aware you've done for her. Or even just spending time in your company may remind her of this, for now.
It's not a very adult way of thinking, to frame the relationship in terms of repayment, as if could even be possible and as if non-repayment is somehow a failure on her part, but she's still young. Some teens do struggle very much with the idea of not being on an 'even par' with adults, in terms of what they can put into the relationship, as this means that they will always be 'in debt' to someone who they currently don't maybe feel that warm towards (raging hormones!). Might take some time for them to realise that this is just the normal parent-child order and the debtor-debtee relationship doesn't apply here.
Just an interpretation, may all be irrelevant.
I also would try not to let one DC's thoughtlessness add to another's so that your overall judgement lands all on one head. They are individuals and it's not her fault that her brother has let himself be bribed before, especially given that he was older than she is now. She'll probably resent being lumped in with him and is likely to focus on that as an example of how you're 'overreacting' (not saying you are) instead of trying to understand you. At the same time, I suppose it wouldn't be bad for her to realise that this is how people do react to things (e.g. reacting to 'the last straw' instead of being able to compartmentalise) and that she won't have the luxury of dealing with people, e.g. in her professional life, who just treat her purely as an individual later on...
I would have a short, calm talk with her. There's nothing wrong with making her aware of your feelings and indeed she should know if something is upsetting you. You're not just there to be a shelter for her, you are a person in your own right. She might then be able to reassure you and maybe work out a compromise e.g. like someone above suggested, getting ready with you on the night. Sorry you're upset, OP. Respect is very rarely allocated fairly, but I'm sure DD will become aware of how much she admires you as she gets older.
