In Western astrology, falling in love and marriage are different house placements.
Falling in love is the fifth house, symbolizing games and entertainment.
Marriage is the seventh house, symbolizing important partners and companions.
Loving each other (sharing joy) is easy, but getting along (sharing hardship) is difficult.
A good playmate may not necessarily be a good partner or business partner.
Therefore, finding a spouse from a romantic relationship may not necessarily be the best approach, and good playmates may also frequently part ways when doing business together.
However, don't be too pessimistic.
The fifth and seventh houses are 60 degrees apart, belonging to the sextile aspect.
Therefore, the fifth house can benefit the seventh, and the seventh house can also benefit the fifth.
Sharing joy and accumulating positive shared memories can help partners and companions enhance their relationships, which does have some logic.
