Capricorn's ambition works well on the outside - Libra wants to show off a successful partner. However, behind closed doors, Libra can feel second best to Capricorn's career and other projects. Capricorn can be neglectful, but also feels a little suffocated by all of the time Libra wants to spend together. If this couple could learn to compromise, it might not be all doom and gloom, but for either of these signs doing that is unlikely.
Another area where these two clash is Capricorn's love of routine, tradition, and stability, versus Libra's airy, spontaneous, and carefree personality. In the best situations, their personalities rub off on each other and they both become more well rounded as individuals. However, what usually ends up happening is they drive each other crazy. Get ready for a very dramatic break up!
