Lol, and I was going to suggest new dirty lingerie and hot sex, seriously. Burn up the sheets, or the carpet, or the kitchen table, or hallway, or all of the above. Make it your dream night of wild sex, ditch the inhibitions. Take a leap toward intimacy and see what happens. After all, H it seems like H is really starting to take a risk himself by moving away from PW and toward you. Emotional risks that build intimacy are a great tandem sport.
Great to see H is starting to come around. My guess is that his sullenness probably had to do with a text or call from PW. If so, her unwanted intrusions will get tedious very quickly.
