These are timely questions with the Libra emphasis coming up. Especially with Saturn in Libra insisting that people really look at who they are partnered with, or want to be partnered with.
If Libra is emphasized in your chart you will not be happy if you're alone. That's a fact. Doesn't matter how many books you read about the joys of being single. Libra is the sign of relationships and Libra needs to relate to someone. Libra is not detached Aquarius or fiercely independent Aries or wandering Sagittarius. This is not a bad thing.
Libra gets all kinds of static for wanting to be in relationships. But you know what... wanting to be with someone is not really the problem. The difficulty arises when Libra sacrifices his or her boundaries/self esteem just to be with someone. Anyone.
If you have planets or angles in Libra there is no doubt that Saturn's passage through your sign has tested you to the max. Restrictions (Saturn) on who you can be with are tough. But Saturn wants you to shore up those boundaries and become uber-selective about who you gift with your presence. And with Venus in your sign, soon to be joined by the Sun and Mercury.....well, you can call the shots if you want.
