Let's take for example olivia1's thread in Your Readings:
what is her problem?
Here are the cards that she drew:
4 wands+3 cups+ emperor & I understand there are no positional meanings.
I had scanned them from the Ithell Colquhoun deck below (note that she starts The Fool as 1 so that The Emperor is 5, not 4 & that the cards have their Golden Dawn titles. And it is 'titles', not 'names').
You quickly see elemental fire running through all three cards, even the middle which is (see the background) elementally water. In the Emperor, the fire element is both internal and forms an aggressive shell, but the violet containing wall is breached. In the last card, the 4 of wands, the fire element is predominant and yet seems soothed and partly contained by the water element. In the central card, the water element prevails but fire swirls through it.
So, her question was, more or less,
why does this person who is not a part of my relationship seem to have such strong opinions about it and a wish to interfere?
The Emperor has a planetary association with Mars (red or scarlet), is associated with alchemical sulphur and is on Path 28 (Netzach/emerald to Yesod/violet). This is a strong energetic card and the influences show the will to power.
With the 4 of wands the fire element is overlaid with the colour of the fourth sephiroth Chesed (deep violet). The colour overlays and to an extent contains versus the Emperor where the element represented by scarlet surrounds and penetrates. Here the fire element is at least partly subdued by Chesed, Mercy.
In the central card, the 3 of cups, the water element prevails, but there is a strong influence of Mercury (words, thoughts) in Cancer (protecting what is 'yours') shown in the swirl of colour.
So, can these be read as true tarot. I think so. Back to the question 'what's her problem?'
She wants to be angry and has to stay (mostly) in control. There is anger at the situation both spilling out (at times as described in olivia1's post) but which she is also forced to contain. A great deal of anger and a desire to be forceful is constrained and held back, forced inaction (it isn't her relationship, she doesn't get the last word). So, she gossips and talks and contains her rage because she doesn't have enough power to take the decisive action she would like, i.e. end the relationship. However, she also has an influence of Chesed, Mercy, and perhaps olivia might try to understand that the other woman is not completely hostile and possibly just wants the best for her friend, the man in the question.
Well, that is the best that I can do and no doubt I got many things wrong.
