Bad fantasy, SD. Let it go and leave it alone. Find another. It won't bring you anything but frustration and grief.
AD: Just a question... have you ever yet flat out told W that the M is on the line here? I mean, have you specifically stated to the effect that this issue is a deal-breaker for you, and if it can't be resolved in a reasonable time frame, you're prepared to end the M over it? If not, maybe it's time. But it's not the kind of thing you want to say in a fit of anger. It has to be done matter-of-factly, without yelling or nastiness. Emotion is good, but the emotion here would be sadness, not anger.
