Both should pay mind to how they deal with arguments and disagreements, especially on Gemini's part because they are so moody and temperamental.
And as their relationship runs longer, their rapport may be at risk of getting bland. Their love for self-preservation and freedom frequently leads them to be less emotionally sensitive to each other's needs, especially when it comes to intimacy and passion.
Both need to work out their emotional stability because both these signs often keep distances and secrets. Spontaneity and a little compromise are what this Gemini-Sagittarius couple needs. Their signs come opposite each other in the zodiac astrology making their personality and perspectives intertwined with each other.
A love relationship between Sagittarius and Gemini is a match made in heaven.
