Your best initial approach is likely to act "as if" you have given her some space and that space has helped.
I agree completely with JB. In the DB book, MWD came back from a trip not sure on how to act and did the 'as if' and it worked.
I tried it out this weekend myself and it worked. As I was driving closer to my house with my stomach turning NOT wanting to get there, I figured why not try that approach, it can't be any worse than walking into a miserable/angry person. It threw my H off and we all had a pleasant day.
