I'm sorry to say, but unless you're ok with YOU being the one trained right now, potty training isn't going to happen in a day for you. That's because she is not ready. First of all, she's only 2. But if she won't tell you when she's wet or needs to go - BIG RED FLAG that she's not ready. If it's a power struggle, she is taking control the only way she knows how - not getting on the potty. SHe's doing this to tell you she's not ready. They need to be physically and emotionally ready to do this. She's just not.
back off for a few months and revisit. She doesn't sound in any way like she's ready. And if she's fighting you, it's not worth the fight. You want her to have positive associations with this.
Children will learn the potty when they're ready. My son was very easy to train because I waited till he was ready. He had been following us in there, we had read lots of books about using the potty, and we talked about it. So he was prepared by us. We bought a potty seat together. But I waited until he was ready, and he learned in just a few days with no accidents (and some naked time to be able to run in there when he felt the need). It happened so quickly because he was ready. BTW, we also use cloth diapers so he didn't have the problem of ultra-absorbent paper diapers. He felt wet. We then moved to cloth trainers because they were easy for him to pull up and down himself.
