Their Mercury in your 7th house

Talking is how you two connect

In synastry, you place one person's planets into the other person's houses. When someone's Mercury, how you think, falls in your 7th house, Bonds, that part of them shows up in the part of your life about relationships, partners, marriage.

What it's like

Long dinners, honest conversations, settling a disagreement by actually discussing it. This person makes partnership feel like a dialogue rather than a standoff.

The good

You can hash out disagreements by talking

The tension

Over-explaining can stand in for feeling

It depends who they are

The same placement plays out differently with a partner, an ex or your mum.

If they're your partner

Talking is how you two connect

You make decisions by talking them through, sometimes until midnight. This person makes you articulate your needs, which is useful and occasionally exhausting.

If they're a crush

They talk like a possible partner

Chat with this person turns to what you each want and expect. It can feel honest, or like being interviewed by someone charming.

If they're an ex

They kept the dialogue going

This person was a talker in your house of partnership, and you built the bond through conversation. Words were also how the disagreements got dragged out.

If they're a friend

They are your sounding board

You ring this person first when you need to talk something through. They're a good listener and an honest critic, in roughly equal measure.

If they're family

They say it straight to you

This person says what they think of your choices, your friends and your plans, often over a cup of something. Honesty is the family currency here.

The other way round: Your Mercury in their 7th house

You become their sounding board

Your Mercury in this person's 7th makes you a natural sounding board. They bring you the dilemmas, and talking things through becomes the heart of the bond.

About Mercury

Mercury is your mind in motion: how you take things in, talk, text, plan and argue. It's also the planet of errands, emails and that list on the back of an envelope.

About the 7th house, Bonds
