Why did my coworker stop talking to me?

Look at the shape before the reason. Three things look like a coworker going quiet, and from your desk they match.

The first is a load that got heavier. Something at home, a deadline, a review. The quiet is everywhere, not aimed, and you only notice it because you were closer than most.

The second is something you said or did, or something they were told you said. That one has a reason, and the reason is the shape. The third has timing: the quiet arrived after the two of you got closer, after the lunch where something real was said, after you became the person they told things to.

This page cannot say what is inside them. It can say what the third shape looks like from outside, and it looks like a body making distance before a choice is made.

For some people, being known at work reads as exposure. They told you something real, and the next morning that felt like more than they could hold in a building they have to come back to. The distance arrives on its own. Then the sentence that would explain it gets heavier every day, and at work there is never a good minute to say it, so the quiet pays for itself.

That is a mechanism, not a character. It says nothing about whether they liked you. Often it says they did.

You keep asking what you did. The quiet keeps answering a question you did not ask.

It is not about the joke in the meeting. If the quiet is far bigger than anything you can find, it is not an answer to the thing you found.

It is not a test you can pass by being more useful. There is no favor that opens a door somebody closed from the inside.

And it is not yours to end. The pull away starts a few seconds before they choose it, in a body you are not in. No message in the shared channel reaches those seconds.

Watch what happens in you when they walk into the kitchen. A tight chest. A pull to say something bright, anything, to test the air. A flush of heat at being the one who always speaks first.

Say one plain thing, once, somewhere private. I noticed things have gone quiet between us. If I did something, I would like to know. Either way, no pressure. Then leave it.

Do not run a campaign. The extra favors, the bright hellos, the question routed through somebody else. Each is pressure, and pressure feeds a pull away. At work it also gets noticed by the room.

Do not match the quiet. Going cold back turns a withdrawal into a standoff, and you both still have to sit in the same meeting.

Keep working as you did. Be civil, be ordinary, and let the thing be ordinary too. A workplace can hold a quiet that a friendship cannot, and that is a relief rather than a loss.

Check what has changed in you. Whether you now rehearse the kitchen before you walk into it. Whether you read their face before you speak in meetings. Whether you have gone quieter with the next colleague, so there is less to lose.

Each of those is a pattern with its own file. The over-bright hello in particular has a body signal you can catch: the tight chest, a few seconds before you speak.

That is the part with a door in it. The person who stops running their own pattern changes what the room is like.

This page cannot answer that about a person it has not met. What it can do is give you the sort: a load that got heavier, a reason you have not been told, or a pull away that arrived after the two of you got closer. Read the timing. If the quiet followed the week you became the person they talked to, it is likely the third. Then say one plain thing, once, and keep working as you did.

A quiet that went everywhere at once is not aimed at you, and that is the useful fact in it. Something in their life got heavier, or the building did. Do not read it as the first shape on this page. Say one ordinary thing when you pass them, and ask nothing. If their quiet comes with other things that worry you, not eating, not sleeping, saying they cannot go on, that is a question for a person, and the number at the top of this page is callable about somebody else.

That question turns the lens around, and this page will not hand you a verdict in either direction. Look at the shape first. One person going quiet is a sort you can run. A whole room going quiet is a different question, and if it is aimed at who you are, the box above is yours. If it is neither, the honest move is to look at your own sequence: the over-bright hello, the favor nobody asked for, the going cold first. Those have a file, and the file is yours to open.

Some people read this page for a coworker and recognize the pull from the other side. The lunch where you said too much. The next morning, when the kitchen felt like exposure.

If that just happened, the first-person file is The Disappearing Pattern, the pull to make distance when someone gets close. It is written for you, about your own body, not anybody else's.
