Hi Alpha, I agree with Twin about the 'doormat' advice.
You say your W is being pretty nice lately. Please don't start to feel this is a sign of change in your sitch. That is likely to take much longer, if it happens at all. It's much more likely that she wants you to co-operate on the sale of the house. By all means be pleasant in response, but plough your own furrow here...
Sounds like you are doing well though...
