Usually, I draw this card for financial inquiries, but in matters of romance, I concur with zfy87060's perspective. The 4 of Pentacles suggests being "tight," "miserly," or displaying a "lack of generosity." It can also signify a shortage of physical energy, akin to when I reduce my dance teaching due to physical fatigue.
In financial contexts, it indicates frugality, but it can extend to emotional aspects. Some individuals are emotionally reserved, while others, like in your positive experience, might be busy or drained, unable to offer emotional energy.
In interpreting your spread, it seems he currently lacks the emotional resources to be generous. It doesn't necessarily imply he's a bad person, but be cautious not to exhaust yourself seeking emotional depth from someone who may not have the capacity to provide it at this time.📜✨
