Just guessing, but I think HP means, at the beginning of a relationship, when all the newness and excitment is present...how do 1s deal with it. I think my W dealt with it by putting on a facade of being sexual, and somewhat carefree.
But, after awhile, she gave all that up and felt freer to be her repressed self. And then, wrote all that early behavior off to "beginning of the relationship stuff."
