Libras are best at fulfilling one key relationship need...
Libra shifts the focus of the Zodiac from the individual to social interaction. Therefore, Libra is one of the Zodiac's most social signs. Your Air ruler makes you a great conversationalist on a wide array of topics, and your datebook is bursting with friends old and new.
You just love being around other people, no matter what you decide to do. Part of this is because being around others makes you feel calm. Being alone, not so much.
Though some may see you as insincere or superficial, you just enjoy getting to know other people on many levels. Once you're closer, you can go pretty deep in your connection.
Once you find your perfect partner, you will rely heavily on them. If for some reason they don't understand or care for your problems, you are susceptible to fall into a blue funk. You want the same attention, love and respect back.
