Mercury retrograde is the period when the planet Mercury appears, from Earth, to move backwards through the sky. It happens about three times a year and lasts roughly three weeks each time. In astrology, Mercury rules communication, so retrograde periods are traditionally linked with misunderstandings, delays, technology glitches — and, famously, exes getting back in touch.
Is Mercury really moving backwards?
No. It is an optical effect caused by Earth and Mercury moving at different speeds around the Sun, similar to a slower train seeming to move backwards when you pass it. Astrologers use the period symbolically, as a time to slow down and review.
What it is said to mean for relationships
- Miscommunication. Messages are misread, tones are misunderstood, plans get mixed up.
- The past resurfacing. Old conversations, old feelings and old partners come back into view.
- Reflection. A natural time to rethink what you want from a relationship.
- Delays. Decisions and big conversations can feel harder to settle.
Exes and Mercury retrograde
The "retrograde ex text" is almost a joke at this point. Astrologers connect it with the "re-" theme of the period: review, revisit, reconnect. If an ex reaches out, the retrograde doesn't decide what it means — it simply invites you to look at the past clearly before you respond. Ask yourself whether you are drawn back by the person or by the memory. If a breakup is still on your mind, see tarot after a breakup.
How to handle it
- Re-read important messages before sending, and ask when something is unclear instead of assuming.
- Give big relationship decisions a little more time if you can.
- Use the period to reflect: what patterns keep repeating in your love life?
- Be patient with partners — misunderstandings are more likely, and more forgivable.
Should you start a relationship during Mercury retrograde?
Many astrologers advise caution with big new commitments, but life doesn't stop three times a year. Plenty of happy relationships began during a retrograde. The practical advice is simply to communicate extra clearly.
Retrograde and your sign
Astrologers look at which sign Mercury is retrograde in, and which part of your own chart it touches, to describe how strongly you might feel it. An astrologer can look at this for you in a reading. For a quick overview of your sign, see our zodiac pages.

Usually three times a year (occasionally four), for about three weeks each time.
Is Mercury retrograde bad for love?
Not inherently. It is traditionally a time for reflection and clear communication rather than a time when relationships fail.
Should I text my ex during Mercury retrograde?
