The Descendent is the opposite sign of your Ascendant, if it is ruled by Aries then you are a Libra rising. What does it mean if your 7th house is ruled by Aries? Remember this is the house of relationships, not just any kind but those that (like Libra) require partnership. For example, the 11th house is associated with your group activities, your 4th house is all about your relationships with family and so the 7th house is in between. Astrologers call it the house of marriage and this is true because marriage is a partnership of two close people. The sign here will show what kind of people you attract into your life or what kind of people you want. Interestingly, it is always the opposite sign to your rising sign that is the one we are attracted to.
Aries descendant people tend to attract a type of person who is: very direct, impulsive, aggressive, honest, simple minded and confident. In other words, they attract people that are ruled by Mars qualities. The Libra rising finds making decisions hard because they need to follow social norms or pleas others, they are always looking for a balance before taking action. Naturally, people that can come into their lives and make it easy to take action are very attractive. The Mars person allows the Libra rising to just relax and stop going up and down in their emotions and thoughts.
The problem is that no one likes to be bossed around-even the Libra person. At some point, you are going to just stand up and say: “Enough! I can’t take this anymore, you never listen to my opinions, my emotions, it is always all about you you you!”
And this is the really secret of the 7th house- it teaches us a lesson. The Libra rising is secretly tired of pleasing others but unable to make it stop, and so they need someone to challenge them and allow them be true to themselves. Then they find out how strong they are- stronger then the Mars friend, girlfriend or husband. They find out that diplomacy is a gift and that they are clever and know how to make the best moves.
The trick is to stand up for who you are and believe in yourself. But what happens in a relationship like marriage? Well allot of passion and arguments- but most of the time its for the better, The Aries person learns to take it slow and be a little more polite to others and the Libra person learns to speak up and be more aggressive.
Either way this is one of the most beautiful couples because they can work as a team and reach the stars together.
Just remember its all about changing yourself and not your partner.
