Does your union seem off? It probably is!
The dating life of a Libra isn't always smooth, but every other sign suffers from that. Like most, you expect to find the perfect companion, and you could go from one love affair to the next until you find it.
People are drawn to your amiable and comforting personality, but your indecisiveness could make you declare your love too quickly. Or you may overthink the process until it's too late and the other person has moved on.
It's also possible that you subconsciously look for people who are bad for you, need to be "fixed," or promise to balance what you feel are your own inadequacies. Practice trusting your instincts more. Learn to recognize when someone has "trouble" written all over them and move on.
