I'm in the same boat. I never attempted, but I've had serious intentions. My wife said the same thing; that she could not be with a woman because she's not a lesbian. My wife is also a lot like yours: emotionally abusive and narcissistic. Can't say that I'm not a narcissist, myself, but I've recognized it and am trying to use it in a positive way. Really, though, we fight like sisters when we get into it, with the difference being that I start shutting people out and go depresso (not a word; it's just how I describe what I do). It's no wonder that we're seen as "twin flames"; we're too much alike, yet we're so different. We decided to remain best friends by separating and then, later, we will divorce. We want to stay part of each other's life, but we can't live together anymore.
