With any of the Twos - and the 2 of Cups is no exception - the challenge is that they are linear and have a narrow field of operation; there can be an insular and claustrophobic feeling to them. A polarity is implied, like an "on/off" switch - something either "is" or "isn't" and it can be difficult to find equilibrium if there is no compensating "back-flow" or circulation of energy to measure your progress against. If not actively reciprocated and brought into balance through feedback, the 2 of Cups can imply emotional "tunnel vision" with no apparent light at the end. It reminds me of constantly pouring water into a broken pipe: you're never going to fill it up unless you step to the side and look at both ends to find the breach and repair it. That's the role of the 3 of Cups, which affords a broader view of the emotional landscape. You might try Paul Fenton-Smith's idea of drawing two more cards to place on either side of the 2 of Cups to see if they shed light on any imbalance that may exist in the situation.
As an aside, I recently had the 2 of Cups as the "near future" card for a client who was in the same situation. But it was reversed, so I told her that - while it looked like something was brewing for her - it was going to take its sweet time reaching her and she would probably have to meet it more than half-way. The preceding card was the 8 of Wands reversed, which reinforced the idea of delayed arrival, and contributed to her sense of anxiety. Together they created an ambivalent outlook for the immediate future. Her redemption lay in the 3 of Wands as the outcome card, which I suggested meant a positive, forward-looking state of "patient anticipation."
