Quick answer
Slow down, breathe out, and keep the interaction short. You don’t need to look unaffected. You need to look steady.
Almost everyone feels a jolt when they see an ex unexpectedly. Your heart races, your face feels warm, and your mind goes blank. That’s a normal reaction, not a sign you’re weak or “still not over it.”
The goal isn’t to hide your feelings completely. It’s to stay calm enough that you can leave the moment feeling good about how you handled it.
What’s actually happening in your body
A surprise like this triggers a quick stress response. Your breathing gets shallow, your voice may tighten, your hands might fidget, and your eyes may dart around.
Here’s what you know: you feel shaken. Here’s what you’re probably assuming: that everyone, especially your ex, can see it clearly.
They usually can’t. Most people notice far less than you think. They’re often busy managing their own nerves.
What to do in the first 10 seconds
- Breathe out slowly. A long exhale calms your body faster than a deep inhale. Do it before you speak.
- Drop your shoulders. Stress pulls them up toward your ears. Let them fall.
- Plant your feet. Standing still looks calmer than shifting or stepping back.
- Make brief, natural eye contact. A friendly glance, not a stare. If you look away, do it slowly and then look back.
- Smile only if it’s real. A small, genuine smile works better than a stretched one.
- Slow your speech. Nerves make people talk fast. Speaking a little slower makes you sound steady.
Give your hands something simple to do. Hold your bag strap, your coffee, or your phone. Avoid touching your face, hair, or neck, which are the most common nervous habits.
What to say
Keep it short. You don’t need to prepare a speech.
If you want to be friendly and brief:
“Hey, good to see you. How have you been?”
Why it works: It’s polite and gives you time to settle while they answer.
If you want to keep it light and leave:
“Nice running into you. I’m in a bit of a rush, but take care.”
Why it works: It gives you a clean exit without being rude.
If you’re caught off guard and need a second:
“Oh, wow, hi. That was unexpected. How are you?”
Why it works: Admitting you’re surprised sounds honest and relaxed. It’s natural, not weak.
If it’s awkward and you’d rather not chat:
“Hi. I hope you’re well. I’ve got to run.”
Why it works: It’s kind but firm. You don’t owe a conversation.
What not to do
- Don’t try to look “over it” on purpose. Acting too cheerful or too cold comes across as forced. Aim for ordinary and polite.
- Don’t rush to explain your life. Telling them how great things are, or how you’re seeing someone, usually sounds like you’re trying to prove something.
- Don’t bring up the breakup. A chance meeting in a hallway or grocery store isn’t the place for it.
- Don’t stay longer than you want to. Two minutes is plenty. Leaving first, calmly, helps you feel in control.
- Don’t replay it for hours afterward. One awkward second is rarely as noticeable to them as it feels to you.
If you get it wrong
Maybe your voice cracked, you stumbled over words, or you froze. That’s okay. It doesn’t mean the encounter went badly, and it doesn’t change anything about who you are.
Don’t text them to explain or apologize. Give yourself a few minutes alone, take a walk, call a friend, or just breathe. Then let it go.
When it keeps happening
If you run into them often, because of the same neighborhood, workplace, or friends, it gets easier with practice. Having a simple line ready, like “Good to see you, take care,” reduces the dread.
But if every encounter leaves you upset for days, that’s worth paying attention to. It may mean you need more space, or more time to heal. That isn’t failure. It’s information about what you need.
Bottom line
You can’t control the jolt, but you can control what you do next. Exhale, stand steady, speak slowly, keep it short, and walk away on your own terms. Calm is a skill, and it gets easier each time you use it.
