The reversed Three of Cups card indicates that there is a blockage in the long-term relationship. This could be a conflict of interest or a lack of communication. This blockage could be caused by personal situations such as financial problems, family pressures or lack of time for the relationship. Furthermore, the charter suggests that those involved may not share the same goals or desires.

The Six of Pentacles card indicates that there is a good chance of finding a solution to the blockage. This card indicates that those involved can take a more collaborative approach to resolving their differences. There is also the possibility that people are able to compromise and better understand each other's needs. The card also suggests that there may be difficult moments in the process but that in the end a mutually satisfactory agreement can be found.

In conclusion, the odds of a long-term relationship depend on the ability of the people involved to overcome the current block. While there is always the possibility that no agreement will be reached, the Six of Pentacles card indicates that there is a good chance that this will happen if you practice collaborative approaches and work together to better understand each other's needs.
