Reading through your post I dont think TUTH is what you need .
A more social/bonding pheromone would be better IMO .
Some IH with I SHINE or Ammo with Shine.
Instant honesty is great for deep connected conversation and bonding, I would mix it with Shine to add a brighter lighter social note.
For seduction mixes have a look at Mobocasters journal.
Other will probably have more advice on some of the Putatives that may be of use to you.
Good luck with you relationship, It sounds like you are managing well under difficult circumstances.
