personally, I think that's better than the alternative... being apathetic...
at least she still has emotions for you...
your are probably right, you don't deserve to be hated... hatred and anger generally come from fear. What you might be seeing is that she is lashing out at you in classic WAS behaviour and just giving you... reasons... but you don't know what her fear is...
time... is your friend... no matter how much you might dislike time right now (hate is such an ugly word)...
let time allow her to cool off and clear her head... before you take any drastic measures...
chances are... in a day or a few or a week... you'll see the elastic band / roller coaster show up...
