Validate her when she talks, keep up with GAL, don't become Super Husband. I think if you can do these things, you are off to a good start.
Don't bring up the R. Let her do that. When she does, validate.
Make sure that you are fun to be around. Hard to do when you are unsure, I know. But you need to be happy. Its much easier for her to walk away from a miserable, anxious, up tight daybyday.
