Why did she become so submissive?

My girlfriend and I have been dating for 6 months, lately, she's been very submissive to me. I can tell her to do anything and shell do it. For example, I tell her to cook, clean and do the laundry, and she does it, without complaining, even when trying to have sex with her she always open to it. But I don't abuse her. She used to not be like that but a normal girlfriend. Since I've been calling her out on her rudeness to me and being more DOMINANT in bed she has been acting very submissive. Why is this, just curious. Thank.
