Should we tell the children together?

If you can deliver an agreed message civilly in the same room, yes — it shows the children the decision is mutual and settled, and it stops them hearing two versions. If togetherness would mean visible conflict, an agreed script delivered separately is the better option. The agreement matters more than the seating plan.

How much should we tell them about why?

Less than your instincts suggest. Children need to know the decision is final, mutual as far as they are concerned, and not their fault — they do not need the adult history, and hearing it burdens them with information they cannot do anything with. “We tried very hard, and we can’t live together any more” does the work at every age.

What if my child barely reacts?

Common, especially with boys and teenagers, and it rarely means what it looks like. Children process big news in instalments — expect the real questions days or weeks later, often at odd moments. Keep the door open, watch behaviour rather than words, and let the school know so someone else is watching too.

How to tell your children you’re separating

There is no version of this conversation that feels good. There is a version that goes well. How to plan it, say it, and hold steady afterwards.

Of everything separation asks of you, this conversation is the one most parents dread — and the one they most want to get right. The reassuring part, as far as it goes: decades of research and the experience of millions of families point the same way. Children cope with separation far better than they cope with uncertainty, conflict and silence. The conversation is where the certainty starts.

What follows is a practical shape for it: what to decide beforehand, what the words sound like at different ages, and what the weeks afterwards actually look like. None of it makes the conversation painless. It makes it clear, kind and survivable — which is what your children need it to be.

Agree the script before anyone speaks

The conversation goes best when it is a delivery, not an improvisation. If you and the other parent can manage it, tell the children together, with a message you have agreed in advance. If a joint conversation is genuinely impossible, agree the message anyway and deliver it separately — the children will compare notes, and the versions need to match.

One sentence on why, with no blame in it. “We have decided we can’t live together any more” carries everything it needs to.
The practical facts they will actually care about: who is moving, where, and when they will see each parent.
What is not changing: their school, their friends, their clubs, the dog.
A time and place with room around it — at home, not at bedtime, not on the way to school, and never in the middle of an argument.

Do not announce anything you have not decided. “We don’t know yet, but we will tell you as soon as we do” is a fine answer. A guess that turns out wrong is far more damaging than an honest gap.

What it sounds like at each age

Under fives need short, concrete and repeated: “Mummy and Daddy are going to live in two houses. You will live in both. We both love you.” They will ask the same questions many times — that is processing, not failure to understand.
Primary-age children want logistics. Where will my bed be? Who takes me to football? Answer specifically, and say out loud — even if they have not asked — that none of this is their fault. Children this age quietly assume it is.
Teenagers need more honesty and less staging. They may have seen it coming; they may be angry, or apparently indifferent, or both within the hour. Do not overshare the adult reasons, but do not insult them with a script written for a seven-year-old either.

Whatever their ages, keep the first conversation short. It is the opening of a subject, not the settling of one.

The three questions underneath every other question

However the conversation wanders, three questions sit underneath it, and they deserve direct answers whether or not they are asked out loud.

“Is it my fault?” Answer it explicitly, more than once, even unprompted: nothing they did caused this, and nothing they could have done would have prevented it.
“What happens to me?” This is the real content of the conversation for a child. Answer with specifics — houses, beds, school runs, weekends — and update them as things firm up.
“Will you get back together?” If the answer is no, be kindly unambiguous. False hope feels merciful in the moment and costs the children months of waiting for something that is not coming.

The weeks afterwards

The conversation is an event; the adjustment is a season. A few things reliably help it along.

Expect the questions again, and again. Each repeat is a child checking the ground is still where you said it was. Same answers, same calm.
Expect some regression in younger children — clinginess, disturbed sleep, accidents. It is normal and it passes; meet it with routine, not alarm.
Tell the school. Teachers who know can watch quietly, and it saves your child explaining a hard term to an unbriefed adult.
Keep the other parent spoken of neutrally in your house, whatever the private ledger says. Children experience criticism of a parent as criticism of half of themselves.
Do not interrogate feelings head-on. Side-by-side conversations — in the car, on a walk, over washing-up — get more out of most children than any sit-down.

Holding yourself together while you do it

You are allowed to be visibly sad in this conversation — children are not damaged by seeing that a big thing is being treated as a big thing. What they should not have to do is manage your grief for you. If it comes, name it and steady it: “I’m sad too. We’re going to be okay.”

Arrange your own support for afterwards — the conversation takes more out of parents than out of children, and the evening after is not one to spend alone with your thoughts and a bottle. This stage is exactly what Rebuild Mode’s early weeks are built for: stabilising the basics, calm scripts for the hard conversations, and a plan for tonight when tonight needs one.
