A break-up could be coming your way today, unfortunately, Libra. As mental Mercury, our cosmic messenger planet of the mind and communication, continues his tour of your zodiac sign and solar first house of identity, he will be cast beneath the shadows of icy Saturn across the sky from you in your solar seventh house of partnerships. This means that your most significant relationship will be greatly tested because you are not seeing eye to eye. In fact, you may feel like your lover is being more critical, judgmental, and demanding of you. This energy echoes both today and tomorrow, so beware.
