Imageer, your wife's "fiend" (Freudian slip perhaps?) may have been very religious but if she was talking to your W to go where her heart leads her, is talking for herself. I sincerely doubt she is talking from her spiritual side. More than likely it helps her justify either her own decisions or desires that she has to do what your W has. My W has a score of friends from the job she just left that had the same attitude. Sadly, my W barely knew them, taking their advice over everyone else she has known for years.
Regarding her being a lesbian or not, I would say she is probably a closeted heterosexual who wants to be accepted by her friend, so she is playing the part.
