...how to say this without saying 'because your life goals suck and mine don't' or 'because I'm not trying to destroy an entire race or two in pursuit of my own personal satisfaction?'

Rogue bit her lip and then spoke, "When I told you I wanted you to be happy, we both knew what I was talking about. Your plan to take over Asgard wasn't makin' you happy. I wanted - an' I still want more for you then just settlin' for revenge and then being miserable for eternity. What you just said to me - I don't know what you want to be free from, what you think I'm fightin' myself about. All I could see was that we were up there, an' I was flying in your arms, and suddenly you were telling me that I wasn't happy. Can't you see how that might make me wonder what I was doin' wrong?"

Now talking, Rogue couldn't quite seem to stop, "And then as I'm caught up in your arms and wracking my brain about what you could be talkin' about, and all I could think of is that you mean my powers. And when was the last time you saw me bein' 'free' at all? When I was near death an' taken over by the voices in my head so that I wasn't even me anymore? Tell me I'm wrong - tell me that wasn't what you meant."

Please. Please don't let that be what you meant. Let me have been ridiculous and wrong.
