I also think she is trying to make choc feel guilty because she herself is feeling guilty. This is called projection ( she tosses HER feelings onto you) and it will worsen until she's ready to look at herself.
And I recognize the " I am a bad W and don't deserve you" stuff as being a combo of self pity and depression (BTDT). That means " I am feeling overwhelmed and I want to be off the hook, so I'll make you feel sorry for me. Then I don't have to deal."
