They decided without you. Their job, their move, how they are handling the thing with their kid. You found out afterward, or were told in passing, and you would have had something useful to say. You said great, and you did not feel great. It bothers you more than someone else's decision has any right to, and you know that.
The advice itself may be good. That is a separate matter from why not being asked stings.
01
What you do when you are not asked
The irritation is the surface. Look at what follows it.
You offer the advice anyway, dressed as a question. Have you thought about... You go back over what they got wrong. You pull away a little and wait to see whether they notice. You tell a third person what you would have said.
If their plan goes badly, there is a small grim satisfaction you are not proud of. If it goes well without you, that can be harder.
Some people can see themselves doing it. I hand out way too much advice to people who are grown and didn't ask for it. Seeing it has not been enough to stop it, and there may be a reason for that. I'm the one who shows up to help and fix. That's how I get close to people. If advice is how you get close, withholding it can feel like having no way in.
There is a cost on the other side. People who keep receiving advice they didn't ask for can start sharing less. So the thing you do to stay close may be producing the distance you were trying to prevent.

What the irritation may be protecting
Go a layer down, to what being asked was doing for you.
"If they didn't need me, why would I be here?"
Being asked may be confirmation that you have a place. Under Needed, someone solving their own problem is not good news about them. It may register as bad news about you.

Being asked may be a way of being picked. Out of everyone they could have gone to, they went to someone else. Under Chosen the decision itself may matter less than having been passed over.

What is under the rule
Underneath each rule is a fear that makes a small omission feel large.
Under Needed, the fear may be that without your usefulness there is no reason for you. If they can decide without you, the question becomes what you are there for.
Under Chosen, the fear may be that if you are not selected, you were not enough to select.
That may be why the feeling is out of scale with the event. Someone else's decision does not usually weigh this much. It may be what not being asked was made to mean.
What would answer the fear is not being consulted more often. Under Needed it is being wanted and not required. Under Chosen it is belonging that isn't a competition.

Two questions, in order
Would you rather be loved and unnecessary, or necessary and taken for granted?
Picture the person who didn't ask. In one version they are warm with you, glad when you arrive, and never once need your opinion on anything. In the other they call you before every decision, take what you say, and never think to thank you.
If the first is the one you would choose, that is the Chosen answer. If you would take the second, and being called is worth more than being thanked, that is the Needed answer.
If you can't choose, write that down as it is. Not enough to tell is a result. Other rules can produce this irritation too. Right is the nearest, and it has its own question. Which stings more: that they did it without you, or that they did it wrong? Without you is the Needed answer. Wrong is the Right answer.
Ruling one of these out is the point. That is how subtraction works: take away what doesn't account for the evidence, and see what is left.
And sometimes you really were the person to ask. If you hold the experience and a decision went ahead without it, being annoyed is proportionate. The measure is whether you can be unnecessary to a decision without it costing you something.

One thing to try this week
The next time someone tells you about a decision they have already made, ask one question and offer nothing. A real question, such as what made you pick that one? It can't be have you thought about.
Then stay in the conversation with nothing to contribute but interest. Notice what that is like. Notice whether they talk more than usual.
Being welcome in a conversation where you are not required, and were not specially picked for, is what both fears say can't happen. One conversation is a small test of that.
Advice nobody asked for is one form of Fixing, and that page sets out the other rules that can produce it.
