Sharing the same house is both a blessing and a curse.

It definitely is. You have the opportunity to have positive interactions with W. She can observe any changes.

But detaching is harder. And she does not get to see what life us realty like without you, which seems fundamental in some cases.

Yes you need to spend time not with W. But when you are with her you need to be the best you possible. Never cold. Good luck.
