It is encouraging that your W stayed on the bed after your comment and participated in the nibbling and petting. Too bad you weren't able to sense her growing discomfort and stop before she had to hightail it out. I guess that's the obvious lesson: if the opportunity arises again, take it slower, stop sooner, let her set the pace. Stop well before she gets uncomfortable, resist the temptation to test the limits. I know, you want so badly to be close to her, for things to be better. She is clearly ready for some amount of closeness, the trick is figuring out how to cultivate that without crossing the "too much, too soon" line that scares her away.
Great news about the in-laws and what W is telling them.
