Hi, I'm parent to 3 sons (2 grown and 1 15-year-old), plus I've taught 5-year-olds for 20 years. This behavior isn't totally unusual for this age. (A baby in the house might explain some of it, too. My sister came when I was 5 and I didn't feel cute and adorable or tended to for a while.)
5-year-olds are very savvy. As with all kids, they want some control in their lives, and they are seeing just how far that control can go.
Kids know when they're pulling your chain, and the more you react, the harder they'll pull. And I also know that 5 is a brief peek into the teen years. Shock value goes a long way for them. Mine used to say I wasn't his mommy anymore and that I couldn't come to his birthday party. Well... obviously he didn't mean that, because I was the one throwing the party. *smile*
I seriously doubt that your daughter hates you. You are her mom, you aren't her friend. It can't be both. You are an AUTHORITY figure, not a peer. But you can be an authority figure in a loving way. Above all, don't argue with her.
Will your husband work with you on coming up with a list of chores that are her own - making her bed, putting up her clothes, picking up things that are hers in other rooms - and each day that she completes the chores, she gets a ticket (you can get a roll at Office Depot). At the end of the week, she can cash her tickets in on a reasonable and inexpensive reward or privilege (princess movie, etc.,etc.). Eventually, you will probably need to add the contingency that she needs to do these without a reminder from you, or once again, it won't be your daughter controlling her own behavior.
Refusal to comply with you should result in an immediate and logical consequence. Something like 15 minutes earlier to bed (if she can't cooperate like a big girl, she can't have a big girl bedtime). After that, for each minute she sits and stalls, it's another 5 minutes off. OUTLAST HER. Don't give in, and don't ever let her know that her little insults are affecting you emotionally.
If she says "I hate you", though, that needs a more serious consequence. A firm "We don't say those words in this family" followed by a trip to a neutral place without distraction or entertainment for 5 minutes should be sufficient. And an apology to you is in order AFTER she has had her time alone. Then tell her you love her.
She sounds like a bright kid - sometimes they can really work your patience (their goal) - but don't let her undermine your position as the parent.
Get in as many snuggling, reading, loving and laughing times as possible. They are more powerful than the most expensive toys.
Good luck!
