I wrote the sentence B for paraphrasing sentence A.
A: I feel scared, because my girlfriend is obsessive about me.
B: I'm afraid of my girlfriend being obsessive about me.
Having written B, I am suddenly confused whether sentence B really means sentence A or sentence C below, because be+being+adjective is used for temporal change of subject.
C: I feel scared, when my girlfriend becomes obsessive about me.
Can sentence B replace sentence A, C or neither?
