How to Write Exes With Tension So Thick You Can Feel It

Because nothing simmers like unresolved history.

There’s no tension quite like the kind that comes from two people who used to love each other… and now pretend they don’t. Writing exes is one of the most emotionally charged experiences as an author—and when done right, it practically crackles on the page.

So how do you write that can’t-look-away kind of tension between former lovers?

Let’s break it down.

1. Skip the Closure

Exes are all about what wasn’t said. If your characters ended cleanly, they’re not going to carry that delicious tension into their reunion. Leave things messy. Let them argue about who left who, or worse—pretend they don’t care.

🗯️ What to write:

• “I forgot you existed.”

• “It was three years ago. Move on.”

• “Trust me. I did.”

We all know they didn’t. And that’s the hook.

2. Lean Into Sarcasm & Subtext

Words are weapons here. Think: banter with bite. Passive-aggressive jabs. Petty remarks that hold a little too much meaning.

It’s not about open declarations—it’s about hiding the truth beneath layers of denial.

3. Let the Body Speak

Sometimes what’s not said is louder than any line of dialogue. Use body language to heighten the tension:

• A glance that lingers too long

• A touch that ends too quickly

• Stepping closer than necessary, then backing away like it never happened

16🔥 Example From 

The Ex I Never Got Over

I go to pass him on the balcony, but he doesn’t move.

Just stands there—broad chest blocking the only way out, arms crossed like he owns the night.

“Still walking away from things you don’t want to deal with?”

I grit my teeth. “Still pretending you didn’t blow everything up?”

He leans in just slightly, his voice low and hot against my ear.

“Only thing I regret blowing was your back out that night.”

My breath catches. I hate that it does.

And I hate that he notices.

Writing exes is about weaponizing history. Every word, every touch, every near-kiss is layered with everything they never got to say—and everything they still feel
