What does upside-down love mean on tarot cards?

Generally speaking, as the first person said, hanging upside down means you can't get your money back. It's important to know what card array you are using, but if you take it again, the accuracy can't be guaranteed, because the divination cycle of tarot cards for the same thing is whether the essence of time has changed.

I'll make a bold guess at what you provided for your reference.

For this relationship, you are not firm, suspicious, unstable and confused about the future.

The other person is a very rational person, who knows what he wants and what he should do. He is not satisfied with his present situation. He believes that he can get more and has been working hard towards his goal. I think tarot cards are not telling you what he thinks of your feelings in this respect, but telling you positively what kind of person the other person is.

Finally, tarot cards want to tell you that no pains, no gains. Your focus should not be worrying about your future, but taking practical actions to maintain your relationship.
