When I played it the first time I played It with traditional chords. The chorus did sound minor indeed except when it went to A, to me it sounded as if it was in the major scale again. However when I played it with dominate 5th chords and using the higher octave of E Fm the chorus seemed to remain minor. I was wondering if the bass notes had something to do with the difference that I heard. The transition was pretty smooth between the two. It was very resolved. Unfortunately my song must stay tense until the end of the 2nd section or it will not make sense.
