Besides the friendlier and more uncertain attitude, there are a few other things.
1. H's spending has dropped way off.
2. H mentioned he was working this past Saturday at the restaurant instead of the store where he was scheduled to be, and where the OW also works, because of "some stuff" at the store.
3. H has begun volunteering more info again about what he is doing and when. H is also responding to my texts and emails again.
