Pentacles can be a physical manifestation of the feelings. A brief run down for me:
Ace of Pentacles - feeling like you have a real shot at someone, will have an opportunity to be physically close, see someone as real relationship material. Start of building someone solid, not fleeting
Two of Pentacles - as Griz beautifully described, this can mean meeting someone, being in their physical presence. It can mean juggling two people, trying to keep the momentum going, testing someone's interest, trying to stay on your good side. Moving your schedule around to meet a date.
Three of Pentacles - admiring someone, working with someone. Open to negotiating through issues, open to meeting someone half-way. Importance of getting along with a third party, building on the initial spark of the Ace.
Four of Pentacles - withholding feelings, shutting off, keeping your opinions to yourself, staying tight-lipped, shutting people out, not budging, being stubborn
Five of Pentacles - feeling unloved, feeling left out, feeling like you're not good enough or worthy. Sticking to someone through thick and thin
Six of Pentacles - knowing something is owed, giving only what you're prepared to give, an obligation, an imbalance, a sexual exchange, giving to someone who needs help, knowing someone will help
Seven of Pentacles - wondering if its worth it, feeling impatient, a sign that the love you have given is felt and will be reciprocated, stepping back and reconsidering
Eight of Pentacles - devotion, dedication, commitment, fascination with details about you, utterly focused. An example, running around to make sure a dinner is perfect, the restaurant is right, the parking is sorted, you've got enough money etc
Nine of Pentacles - admiring a beautiful and independent woman, someone not threatened by your independence and success, someone who is happy to be on their own, someone who is self sufficient
Ten of Pentacles - building a solid family life, meeting the family, fitting in with their heritage, thinking long term, purchasing a beautiful home, impact of family's legacy
Page of Pentacles - being fascinated by someone in a new way, noticing someone for the first time, admiring someone's beauty, wanting more physical closeness, outwardly demonstrating interest
Knight of Pentacles - shyness, being humble, slow to move, slow to approach, feeling perhaps that they're not good enough, devoted, committed, slow to get to know you, slow to open up
Queen of Pentacles - the secure woman, the stable woman, earthy sexiness, sensible, practical, the "other" woman, the wife, runs the home, not necessarily exciting or stands out but dependable. The type of woman that you feel wouldn't reject you
King of Pentacles - Committed man, family man, manages money, cares about finances, home man, settled, happy, a bit boring but dependable. Wants to take care of you
