The two signs in this match are air signs and this should make for similar attitudes, feelings, and intellect. They are both curious, fun-loving and affectionate, and are stimulating companions who will enjoy a light hearted, delightful affair. They each have a need for constant change and share a love of a very active social life.
They will not have many arguments, as Libra strives for peace and harmony. However, Gemini tends to look on debates as a bit of fun and mental challenge, and needs to understand that Libra will usually want to avoid a disagreement at all costs.
This could be a rewarding union for these two, as they both feel that a relationship must always be worked at. Libra will be forever expressing their love openly at every opportunity, and Gemini's love for love will feed on these declarations and make them more secure in the relationship. This could be a highly successful match.
