This page is for the days before that evening, not the evening itself. There is no version of the wording that lands cleanly. There is a version that's honest and timed well, and that's the one to aim for.
The question to ask yourself first
Before the wording, sit with a quieter question: why now, and what are you asking her to do with this? "Now" matters because the answer changes what the conversation is. Telling her because you can't carry it any longer is a different conversation from telling her because you want something to change between you.
If the honest answer is "I want to stop hiding", the conversation is about you and what you've been holding. If the honest answer is "I want us to renegotiate the marriage", that is a much bigger ask and she will feel the difference within the first minute. Neither answer is wrong; conflating them is what tends to go badly.
You don't have to know the answer perfectly. You do have to know it well enough that when she asks "what does this mean for us?" — and she will — you aren't deciding live in front of her.
The three reasons men tell — and why one of them needs more thought
Most men telling a wife are doing it for one of three reasons, sometimes overlapping. The first is relief — the weight of holding it has become heavier than the risk of speaking. The second is honesty — a sense that the marriage shouldn't be built on something this large left unsaid.
The third is a request for change. That might mean openness, or space to act on the attraction, or simply permission to stop pretending it isn't there. This third one needs the most thought, because she will hear it whether you say it explicitly or not.
If a request for change is in the room, name it. Don't let her work it out from your tone three days later and feel ambushed. The conversations that go worst are the ones where the man said "I just wanted you to know" and meant "I want us to talk about an open marriage".
What she's likely to ask
You can't script her, but you can prepare for the questions almost every wife asks. She will want to know how long you've known. She will want to know whether you've acted on it, and with whom, and when.
She will want to know whether you still find her attractive, whether the marriage is real to you, and whether you're leaving. Those four questions, in some order, are near-universal. Have answers — short, true ones — ready before you sit down.
"How long" is the question men most often fudge, usually out of kindness. Don't. If you've known since you were sixteen and you're forty-two, the honest number is twenty-six years; rounding it down to "a few years" buys you nothing and costs you credibility when the real answer surfaces later, as it tends to.
What the first hour can actually look like
The first hour rarely goes the way you've rehearsed it. She might go very quiet. She might cry — sometimes immediately, sometimes ten minutes after you've finished, sometimes not until she's in the bathroom. She might ask the same question four different ways because she's looking for the catch.
Some wives go into administrative mode — practical questions about timelines, who else knows, whether anyone can find out. That isn't her being cold. It's her brain doing the thing brains do when they're handed something too big to feel all at once.
Some wives get angry, and the anger lands on something small — a holiday you didn't take, a Christmas card you forgot — that doesn't seem related. It is related. Anger is sometimes the door grief uses on a Friday evening when there isn't another one open yet.
Some wives leave the room. That doesn't mean the conversation is over. It often means she needs ten minutes to be a person before she goes back to being part of a couple having this conversation. Let her go. Don't follow.
What you'll feel during most of this is a strong urge to fill silence with explanation. Resist it. The silences are how she's processing; talking over them gives her less to work with, not more.
Timing, setting, and the things that ruin both
Pick a weekend evening, at home, with no plans the next morning — not a Sunday night before a Monday school run, not a holiday, and not her birthday week, your anniversary, or any date she'll later associate with this for the rest of her life if she can avoid it.
Have the children out of the house, or asleep with the door shut. Don't drink first; don't get her to drink first. Phones face down, television off, no podcast playing in the background to soften the silence — the silences are part of the conversation.
The things that ruin the setting are mostly small and mostly avoidable: a timer on the oven, a delivery driver, a flatmate due back at ten. Clear the runway for at least three uninterrupted hours, even if you only end up using forty minutes of them.
What not to do
Don't tell her in writing. Not by text, not by email, not by leaving a note. Writing removes her ability to ask a follow-up in the moment when her face is doing something her words aren't, and she will resent the cowardice of it for longer than she'll resent the content.
Don't tell her after a fight. The conversation will be heard as a weapon — a thing you produced because you were losing the argument — and that framing will outlast the original disclosure. If you've just had a row, wait two clear days at minimum before you raise this.
Don't combine it with another bombshell. If you're also telling her you've lost your job, or you've been seeing someone, or you want to leave, those need to be separate conversations on separate days. Stacking them is what turns a difficult evening into the worst night of her life, and she will remember the stacking.
After the conversation — the long arc, not the moment
The first hour rarely tells you much in the long run. People say things in the first hour they take back in the first week, and people stay quiet in the first hour about things that come out angrily on day three. Don't grade the conversation by how it ended that night.
The arc that matters is the next six months: whether she comes back to it on her own, whether the two of you can sit in the same room without the disclosure being the only thing in the room, and whether you can be honest about ongoing feelings without it becoming a fresh wound each time.
If you're somewhere further along — already managing the long arc, already redrawing the rules — the bi-and-married page covers the practical shape of staying together, and mixed-orientation-marriage walks through the longer-term arrangements couples actually settle into.
When to involve a couples therapist
Therapy isn't always the right next step, despite what the internet tends to say. If the disclosure landed and you're both communicating, sometimes the best thing is to leave the conversation alone for a fortnight and let it settle. Adding a third person too early can make a private thing feel processed.
Therapy helps when the conversation has stalled — when she's stopped asking and you've stopped offering, and the silence has set into something colder than either of you wanted. It also helps when the request for change is on the table and neither of you has the language for renegotiating a marriage. Look for a therapist who works with mixed-orientation couples specifically; Pink Therapy (pinktherapy.com) keeps a UK-wide directory of LGBTQ+-affirming practitioners, and Relate (relate.org.uk) is the standard general option.
A short note on outcomes
Plenty of marriages keep going after a conversation like this. Some don't, and the ones that don't are not always the ones where the husband handled it badly.
Honesty doesn't always reward you. We won't pretend it does. Some wives will hear what you say and decide the marriage they signed up for isn't the one they're now in, and that decision is hers to make and not a sign that you should have stayed quiet.
What honesty does is end the slow private business of being a man who isn't being seen by the person closest to him. That's worth the conversation, even when the conversation is hard, and even when the outcome isn't the one you were hoping for. If you're earlier in the process than this page assumes — still working out what you'd even be telling her — coming-out-later-in-life is the better starting point.
