Hello Hope,
What can happen between a man and a woman is always noble and has nothing to do with the petty, primitive stories of hormones, but rather with a state of mind and communion in a shared search for osmosis.
Friendly relationships with the opposite sex cannot be ruled out on the grounds that one is married; this seems obvious to me, because logically, one cannot live in a marital cocoon with just two people without being surrounded by various friendships.
For me, the principles of loyalty and nobility of soul are expressed through respect, listening, and candor toward others, rather than through the pursuit of immediate gratification.
To answer your question, YES, the tarot does indeed have a direct connection with these beautiful developments, but unfortunately many of us do not have the patience to wait and see things evolve, and therefore seek an immediate answer to their questions or desires.
Coming back to the subject of friendship, I often say that "friendship is often more present and stronger than love."
P.S.:
Regarding the possibility of creating an automatic reading focused on friendship, I advise you to contact Tom, the administrator of the AZ site.
Nice to meet you
The magician.
