How do I reply to a hostile message from my ex? A free text tone checker for co-parents
For separated parents, a text about a late pick-up can turn into a row about the whole relationship in three messages. Written messages lose tone of voice, and they are easy to send in the heat of the moment. This article explains why co-parenting messages go wrong, how to reply to a hostile message from an ex, and how a free tool, the Mediation Guide Text Tone-Checker, helps parents check a message before they press send.
How do I reply to a hostile message from my ex?
To reply to a hostile message from an ex, answer only the practical point, in two or three sentences, and leave the rest. Do not reply straight away if you are angry. Pick out the one thing that needs a decision (a time, a date, a payment), state your answer or ask a simple question about it, and keep the children at the centre. If the message contains threats or makes you feel unsafe, it is a safety issue, not a wording issue, and needs support rather than a reply.
Why do co-parenting messages escalate?
Co-parenting messages escalate because they often carry two messages at once: a practical request and a judgement about the other person. The other parent answers the judgement and ignores the request. Messages about the past ("you always", "you never") and messages about character invite a defence, and a defence invites a counter-attack. Messages about the next arrangement invite an answer.
What is the Mediation Guide Text Tone-Checker?
The Mediation Guide Text Tone-Checker is a free tool that checks the tone of a draft message to a co-parent and suggests clearer wording. Mediation Guide (mediationguide.co.uk) is a free guide to family mediation in England and Wales, published by Family Legal Ltd. The tool rates a draft's temperature as clear, warm or hot. It was reviewed by Chris Yaffes, an FMC-accredited family mediator (FMC URN 0961A), and is free with no sign-up.

What does the tone checker do?
The Mediation Guide Text Tone-Checker does three jobs. It gives rewritten versions of common co-parenting messages for typical situations, such as lateness, money and screen time. It checks a draft you have written and flags wording that is likely to start an argument. And it breaks down a message you have received, separating what needs an answer from what does not, then gives you a frame for your reply.
What are the four rules for co-parenting messages?
The tone checker is built on four rules that family mediators teach separated parents:
- Keep it short. Two or three sentences usually work better than paragraphs.
- Stick to facts. Dates, times, places and arrangements, with no comments on character.
- Face forwards. Ask about the next handover, not the last one.
- Centre the children. Frame the request around what the children need.
What does a better message look like?
These three examples were written for this article. Each shows a draft that is likely to start a row, and a version that is more likely to get a practical answer.
| Likely to start a row | Likely to get an answer | What changed |
|---|---|---|
| "Typical. You've booked a holiday in MY half-term week without even asking." | "I had the February half-term week down as mine. Can we look at the dates this weekend and swap a week if we need to?" | States the clash as a fact and proposes a fix |
| "She came back with no reading book AGAIN. Do you even look at her bag?" | "Her reading book didn't come back on Sunday. Could you pop it in her bag on Wednesday so she has it for school?" | One request, one deadline, no verdict |
| "If you can't be bothered to pay for school shoes, don't expect to see them this weekend." | "School shoes were £42. Could you cover half by Friday? Happy to send the receipt." | Separates money from contact, which the court treats as separate issues |
Is the tone checker AI?
No. The Mediation Guide Text Tone-Checker uses simple pattern rules rather than a generative AI model. The tool's page states that the check runs entirely in the user's browser and that nothing typed is sent or stored. The trade-off is that a rule-based checker understands context less well than a large language model, so it can miss sarcasm or coded language. Some subscription co-parenting platforms, such as OurFamilyWizard, use generative AI for tone suggestions inside a wider app with calendars and expense tracking.
Why do the wording and record of messages count?
Message threads often reappear later: in mediation, in conversations with Cafcass, and sometimes in court bundles. A thread of short, factual, child-focused messages shows a parent trying to make arrangements work. That is a practical reason to write each message as something a judge, or one day your child, could read.
When is a tone checker the wrong tool?
A tone checker is the wrong tool when the problem is safety rather than wording. Where there is domestic abuse, intimidation, coercive control or threats, the priority is safety and support, not a more careful message. The Mediation Guide tool shows domestic abuse support when it detects threatening language, including the National Domestic Abuse Helpline on 0808 2000 247 (free, any time). In an emergency, call 999. The tool itself states that it does not identify abuse and must not be used as a safety assessment.
What if careful wording still doesn't work?
If every exchange still becomes a row, the arrangements usually need structure rather than better wording. A written parenting plan removes the need for many messages, and family mediation can agree communication rules alongside the practical arrangements. Before applying to court about children, you usually need to attend a Mediation Information and Assessment Meeting (MIAM), unless an exemption applies.
Frequently asked questions
Is there a free tone checker for messages to my ex?
Yes. The Mediation Guide Text Tone-Checker is a free tool with no sign-up that checks the tone of a draft message to a co-parent and suggests rewording. It runs in the browser using simple pattern rules, and its page states that messages are not sent or stored.
Should I match my ex's tone if they send aggressive messages?
No. Short, factual replies give an argument nothing to feed on, and they create a record showing who kept the focus on the children. If aggressive messages become threats or a pattern that makes you feel unsafe, contact the National Domestic Abuse Helpline on 0808 2000 247.
Can a tone checker detect coercive control?
No. A tone checker looks for language patterns in a single message, and coercive control is a pattern of behaviour over time. The Mediation Guide Text Tone-Checker states that it does not identify abuse. Anyone worried about coercive control should contact a domestic abuse service.
