As a combination, Leo and Libra are well-balanced. Libra is charming and cultural, and has good manners which offset Leo's direct and caustic personality. Leo is far more decisive than Libra and can help them to make decisions more easily and act on them, and they can teach the art of spontaneity.
Libra's loving playfulness blends wonderfully with Leo's dash and vigour. Libra is indecisive and Leo will naturally take charge. Their finances may be on shaky ground as together they share a love of luxury, going to parties, and creating a beautiful home that serves as a stage setting for these two stars.
Libra does have to approach Leo carefully on matters involving ego, but that won't be a problem for tactful Libra. In a real conflict, Libra knows how to yield gracefully.
Each partner brings to the relationship what the other is missing, so theirs is a highly compatible relationship.
