Try not to answer. That sounds like a rhetorical statement not a question anyway. Try to avoid conversations where this comes up. I would probably answer with nothing more than, "You're a great person too."
Any statement that contradicts her will only make her start listing the reasons why you can't live together. Or maybe make her think, he has to argue with me even now! Let her talk. Most women complain their men don't listen. You listen, don't argue, debate or fix, listen. An attentive man is enough to throw most women for a loop.
Once upon a time it was easy between you two, yes? Occasionally, it probably still is easy. Sometimes you can make her laugh? What is happening then. What were you doing then? Try to think and operate in that mode and stay as far away from R talks as you can.
You might want to ask WAW1978 or Sandi2 to take a look at your thread. They could offer some female perspective from the other side of the fence.
