She sounds pretty immature. If she were to actually apply logic, then there would be no true problem. Her rage/bitterness towards you could be possibly fueled by her low self esteem and jealousy, thus making a hellish existence for you in the relationship. If it were me, I would leave her. People who are too thick headed to comprehend when one is truly sorry for only talking to another person about their burdens is a huge no for me. Either she makes some growing up to do, or you move on.
