This is how Libras can prevent attracting bad partners...
You are a great catch, Libra. You are brainy, charming and good to the eyes, the whole package! People fall in love with you at the drop of a hat. And the effort you put in getting along with all kinds of people makes you even more desirable. Everyone likes you!
Libra's ruling planet of Venus is the planet of love, which means that one of your sign's prime directives is feeling and expressing affection. As such, your heart opens very easily. Your home, not to mention calendar, may be filled with strays of all kinds if you're not careful, though.
It's great to be kind. But boundaries are always crucial for a Libra. Taking on too much can make you unbalanced and unhappy, which can lead to you feeling resentful. Measuring out your affection at first can help you from falling for the wrong ones, and thus having lots of unhappy break-ups.
