Not sure if she wanted you to follow her up for a "nap". If it were me, I would have invited my H to join me if I were trying to drop hints. Maybe she is trying to see if you will initiate when she just flirts. If your goal is not to initiate at all (which I think it is...) then you are doing great. She will see that she has to be a little more aggressive next time!!
You are doing a great job with a very touchy (no pun intended) subject!
Happiness is like a butterfly: the more you chase it, the more it will elude you, but if you turn your attention to other things, it will come and sit softly on your shoulder.... (thoreau)
