Your Spouse Palace contains Tian Tong, while your partner's Life Palace contains Wu Qu. That difference does not establish that you chose the wrong person. The two labels belong to independently calculated charts and are not required to match.
Your relationship palace is not their birth chart
Traditional readings use the Spouse Palace to discuss relationship themes, expectations or impressions of a partner. Even a reading focused on the partner's image cannot substitute those stars for the partner's actual natal placements.
Imagine one person wanting a relaxed conversation while the other prefers direct decisions. That difference can be discussed without assigning each person a rigid star-based personality. An argument does not prove that their chart labels failed to match.
Keep both people in a comparison
A two-chart reading should retain each person's birth data, palaces and transformations. If it uses a particular relationship method, name that method rather than selecting whichever marker supports a negative conclusion.
Bring a specific pattern: perhaps conversations about spending become tense while shared projects go well. Ask whether the interpretation distinguishes those situations, and keep the mismatches in the record too.
Traditional chart comparison cannot certify a relationship. Respect and willingness to work through problems are matters of behavior. Different star names are not a reason to replace a partner.
