Wyf of Bath?

I know most people are talking most the Wyf of Bath's actual tale, which I really liked, but I wanted to discuss temperament because I think her character is so uniquely fascinating. From the text, we can gather that she is a petulant, vain, wanton, outspoken, and self-serving woman -- none of which is admirable in any way to the other pilgrims, especially the clergy. My question is this: In class, we talked about how the Wyf of Bath wanted approval and all these qualities show her need for acceptance. However, if she so desperately craves acceptance, why does she act the way she does? Wouldn't it make more sense for her to act less like a modernized woman, and instead try to blend in with everyone else? I suppose she can't do this because of her need for control, so maybe I answered my own question in a roundabout way... Anyways, if anyone else has any answers, please share.
