Perhaps my answer would be that monogamy is an unrealistic, unobtainable goal for many and that is a product more a superimposed moral code than the reality of human desire
Man, did you really just say that? Perhaps that's your answer? Perhaps?
Well is it or isn't it?
And is that what you want? There is plenty of monogamy out there - it's not a quaint notion subscribed to by only a few. If you want monogamy, insist on it. And if your W can't deliver, then start working toward what you want.
Get unstuck. Determine your goal and start working toward it. Lead. W will either align with your goal, or she won't.
The alternative is that you aren't what you want, and you aren't what she wants. And that is no way to live.
