Just try to treat your W like she's the neighbor from next door or so. I know exactly how it feels when W is around. I live like this. It's hard and we get nervous and think way too much!!! Just do your thing...if she wants sth she will tell you. Try to "ignore" her, not ignoring when she talks to you but just try to blend her out.
