Great idea for a thread.
I enthusiastically second Rbt’s suggestion of P74 and would also suggest EST. 74 goes with everything and seems to help reconcile components that would otherwise pull in different directions.
A smidge of TAK might prove helpful in dampening anxiety/making each of you feel utterly comfortable with each other.
P86 might help loosen up conversation if one or both of you is a bit reticent.
I don’t yet understand the nuances of the Chemical Romance series (from memory the mixes around the 150 mark), but they certainly seem to be creating some kind of a bonding effect for me - as well as smelling delicious.
Wrt nesting I guess there is the cuddly, staying at home swaddled in cotton wool pole and there is the go out and forage for food and nesting materials pole. I think everything I have mentioned is more of the former pole - perhaps MeoEST, TAF, Safari might help encourage the latter. I’m not sure.
