It's not as dire as you might think. The 5 of Cups often reflects someone realizing they've made a mistake and wishing they could rectify it. It could be that they're only now recognizing the depth of their feelings for you, regretting not asking you out, or not marrying you when they had the chance. They express sorrow for ending things, being unkind, dismissive, or thoughtless.
However, the remaining cups indicate that they aren't considering the positive side—perhaps realizing they can still have you if they demonstrate the right feelings instead of dwelling in remorse. Their emotions toward you are tinged with regret. 🫂
