Lie detector questions

46 replies

Needanewoneforthis · 29/11/2025 23:14

Hi all, I need your help!

I don’t know where to start really or how much detail is required, but if I told the whole story I could be writing this all night!

So basically my ‘D’H has fucked up big time (we’ll call him DH because it’s quicker than husband, even though he’s definitely not dear) and he’s offering to do a lie detector test to allay some of my concerns/suspicions.

Has anyone ever used a polygraph test in a relationship? How does is work? Would I provide them with a list of questions to ask DH? Would I be present? What if the questions need to be altered depending on his previous answer? How long would the test take? How and when do they communicate the results? Presumably the questions can only be based on facts about what he has/hasn’t done, and can’t be based on feelings or what’s ifs/what did you thinks?
Sorry I know I have a lot of questions, but I’ve been reeling for a while.
Also if anyone has any recommendations for reliable companies with accurate results.

Right, so then I need to know what to ask, and that’s mainly where I need your good MNers help because I don’t want to miss anything, I don’t want there to be any wriggle room etc.

I’ll give you as short of a summary as I can manage, but I’m happy to answer questions or give more detail or info if required.

Together 20 years, married 12, DD age 11, DS age 9. If relevant I had cancer soon after DS was born and I can’t have more children.

13 years ago DH started a hobby where he struck up a friendship with a woman who may or may not have been an emotional affair… he always denied it but when I called him out and said it made me uncomfortable based on things I’d seen, he started doing the hobby elsewhere and cut off contact with the woman.
Earlier this year I discovered that DH started speaking with this woman again around 3 years ago and even though the friendship this time I can see was purely related to the hobby, it was still constant, and resulted in 18 months ago him asking her to volunteer at the place he had set up for this hobby himself. She had been involved ever since and he’d never told me. They had spoken regularly and seen each other a few times. I believe it was all above board and professional rather than even friendly, but I was furious that he’d purposely hidden it and been deceitful. His way of apologising for that and trying to make amends was to basically do anything I asked of him - he moved out to give me time and space and moved in with his friend for a couple of months, then was in a short term rental a couple of hours away near work. He started therapy about his lying, deceit, about putting this hobby/this woman before his family. He cried, he promised he’d do whatever I needed of him. Over time he’s gradually ended up back in the family home, and although all was not forgiven, things seemed to have gone pretty much back to normal. But I emphasise that that was just a gradual process, there was no big reunion or conversation, we just found ourselves back to how we were pretty much.

Ffs, this is going to take ages to explain… I apologise. But I’m so grateful if you’re sticking with me.

Anyway, two weeks ago he left his laptop open and went to answer the door and was gone ages. His text messages were open on the laptop and I saw 5 messages at the top from different numbers with just the summary/top line of the texts, which read “Are you working tonight?”, “Up to her, but if she agrees she will charge extra”, “£100 for one hour”… you get the picture! My heart stopped for a minute, but obviously I opened and read the messages. All prostitutes obviously. I confronted him as soon as he came back into the room. To summarise, he claimed when he’s been away with work he’s been contacting escorts/prostitutes but claims he’s never met up with anyone. He handed over his phone and there is nothing confirming he definitely has slept with any of them, but there’s awful stuff on there about what they offer, what he wants them to do, where he’s staying, can they send more pictures and videos. Honestly it’s sickening. He claims it was wank fodder but he never had any intention of going any further. Even if that’s true, what’s to say it wouldn’t have gone further if I’d not found out.

He said that he started doing the above after he’d moved out of his friends place and was alone in the rental near work. I asked lots of questions, I did lots of investigating on his phone and laptop but he’d covered his tracks quite well and admitted most of what he’d done had been deleted. He was a grovelling mess and said he’d do anything to make things better, he’d do anything I ask of him and he’d never do anything like that again at.

A week passed where quite honestly I was just on an other planet, switching between sad to furious, to numb, but as far as the kids were concerned nothing had happened. I wasn’t ever nice to him, but nor was it clear to them that I was upset or annoyed with him or about anything. DH offering the world to me and crying and apologising and whatnot. He went for an STD test (clear), he logged me into everything of his so I could check anything that was doing or had done. After a week or so I asked for his phone - he’d told me he’d deleted stuff as and when it had been happening but I looked through his blocked contacts. I Googled every phone number and lots of them were the city where he worked. Then I found a load from the city where we live… he’d claimed he’d only ever sought out contacting people when away with work. With my new info he admits that actually he started contacting prostitutes as soon as I kicked him out earlier this year when he was staying with his friend. Says him and friend would sit together of an evening messaging prostitutes and comparing notes. He didn’t tell me this apparently when caught out and questioned initially because he knew I’d find it weird.
He eventually moved out of friends into the rental a couple of hours away and continued with this prostitute messaging but never spoke of it again with his friend.

So yes that’s where we’re at now.

To be clear, this dick head (DH) is out on his ear, but in all honestly, I do feel like I need to know all the details. I hate lying and I don’t feel like I can settle and move on until I know all that there is to know. What I do know and what he’s admitted to is end game regardless, but I just want to know for definite what he’s done completely. I need to know.

He has volunteered allsorts to show me how apparently sorry he is and to show how much he wants to win me back and fix the situation, but I can never un-know what I now know, and I’ll always know what he chose, so I’m done with him regardless of his begging.

But back to the lie detector test he’s offered to do. I know some people will think it’s a waste of time, and I appreciate that some might want to offer well meaning advice about it not being necessary because we are done, the marriage is over. But for me it is necessary, so I am specifically looking for advice on lie detector tests and what questions I should be asking this piece of shit who has clearly not been the person I thought he was for the last 20 years.

Please can you hit me with the questions I should be wanted asked during a polygraph test? That’s mainly what I’m here for your help with, but I realise I might need to start new threads for this whole sorry fuck up somewhere down the line. I’m thinking questions like “Have you had sex with anyone else during our relationship?” and then if yes, where does that lead? Like Who with, when, how many times, was it an affair, were you cheating or messaging whilst I was going through chemo? I don’t know what direction his answers will lead and if the questions can be altered accordingly, but I will happily sit here and consider every single suggestion.

I so appreciate anyone who has read this far, and I’m sorry that this post is so bloody rambling… I’m not drunk or having a manic episode, I’m just in the middle of my marriage and family falling apart.

At the point when you are considering lie detector tests, your relationship is over.

You’ve said that you are done. Move on, knowing that you deserve better. You already know that he lies and cheats, don’t torture yourself any further.

You won’t get any closure from him or a lie detector.

IntrinsicWorth · 29/11/2025 23:18

A polygraph is a waste of time and plus, where on earth would you get one in the uk? No-one uses them because they are invalid.

OP, I’d maybe suggest putting this one through AI and seeing what it comes up with ;)

BoxOfCats · 29/11/2025 23:19

Do not do this. This relationship is dead in the water. Of course he has slept with them. And the trust is gone regardless. Time to move on from this.

blacksax · 29/11/2025 23:20

What's the point? He's a revolting piece of work. Just divorce the bastard.

PinkPonyClubDancer · 29/11/2025 23:23

I wouldn’t waste any more time or money on a lie detector test. Divorce him, you deserve better.

Needanewoneforthis · 29/11/2025 23:24

Also to add, he has been speaking with the therapist/councillor since I first kicked him out and continues to speak with her. It had all been about what I need from him and how he can change to be the person I need in the marriage. They’d obviously touched upon other stuff like childhood etc, but ultimately the end goal for their seasons had been to see things from my perspective so he could be a better husband and father.
He’d obviously not told her about his prostitute contact, and it baffles me that he was having conversations with her for months about how he could save his marriage and regain my trust, but he was doing this!
I therefore don’t feel that him speaking to a therapist is working, because look what he’s started doing AFTER starting his sessions with her.
I was in on his session with her last week (first time I had been) when he told her about these new revelations (the prostitute messages) and she said “What the fuck?! I don’t even know what to say.”
DH plans to continue with her but yeh like I say, how much good is it doing if he’s started being even more deceitful and disgusting after he started with her and during a period when he was supposed to be fighting his hardest to repair his marriage?

Sorry, this update is probably for another thread and probably not even relevant to my OP asking for lie detector questions, but there it is anyway.

Polygraphs are highly unreliable and can be easily beaten.

If you want to stick your husband on a polygraph, the relationship is already fucked.

What will you do if he passes it?

What will you do if he fails it?

What will you do if it's inconclusive?

mumofoneAloneandwell · 29/11/2025 23:35

I couldnt finish your op, sorry girl, but its clear from the outset that this marriage is over

Polygraphs are unreliable and your man sounds like he will just find a way to fake the results anyway

Just divorce him girl xx

ReleaseTheDucksOfWar · 29/11/2025 23:52

I'm told by someone who should know that they can be easily beaten. I'm sure he knows that too.

Hes still playing games of deceit and lies with you, I'm afraid.

BigBoots67 · 29/11/2025 23:59

“It was just wank material”

it isn’t. This is textbook. It’s a cliche answer punters give when caught by spouses.

vitalityvix · 30/11/2025 00:04

Don’t do the lie detector, it’ll just pull you back in without giving you any certainty. He can’t lose by taking the test.

If it says he hasn’t shagged them, you’ll feel relieved and he’ll play on that.

If it says he has shagged them, he’ll put on a big performance of shock and say they are inaccurate. You won’t know what to believe.

Focus on what you know for sure - your husband has been messaging sex workers for sexual relief. If he hasn’t already progressed to meeting them (and that’s a big if!) he will.

That’s all you need to know.

Needanewoneforthis · 30/11/2025 00:39

I suspected the replies would be as they have been and I appreciate them, I really do and get what you’re all saying.
But I didn’t realise I was being naive in thinking a lie detector would be such a big no go. Is it really not possible to get an accurate lie detector test done?

Honestly this marriage is over and done, there’s nothing he can say or do to convince me he will change or whatever, because even if he truly did I would never believe him again. Plus what he’s done so far is enough.

But regardless I really do want the detector to be done - the outcome being good or bad wouldn’t matter, I just need to know all the facts. Do you know what I mean? I fucking hate not knowing and I need to know. He’ll not be able to win me back even if he passes it, that ship has sailed.

OP posts:
Needanewoneforthis · 30/11/2025 00:41

Again, I’m truly grateful for the supportive and reasoned responses, but is there nobody who can help with what questions I should ask if I was adamant that it was done?
Thanks to the PP was suggested asking AI

LovesLabradors · 30/11/2025 01:02

Thinking back to things like the Trisha show, & the awful Chris Watts case, men often think they can beat lie detectors - when they often can't. I also learned during my psychology studies that lie detectors aren't admissible in court here in the UK because they are unreliable. So I don't know where that leaves you!

But you already know he's a liar. You want to know if he's still lying I assume? I can understand that - but I think a lie detector test will just have you wondering "did he beat it, or how do I know if it's reliable?" Or he'll be shown as a liar but insist it's wrong.

I think it maybe more helpful to you to accept that he lies and you'll probably never know the full truth. What you know already is enough to end the marriage - and tbh reading your OP, I personally would think the absolute worst. I think there's every chance he's been lying and cheating throughout your marriage. Sorry OP - spend your time, money & energy building a new life for yourself and living it well 💐

it isn’t. This is textbook. It’s a cliche answer punters give when caught by spouses.

It's the answer every man gives when found out. I wonder if prostitutes actually make any money, if all they ever do is message men and never meet up with them 🤔

JamesClyman · 30/11/2025 11:15

Is it really not possible to get an accurate lie detector test done?

No. That is why they are not admissible as evidence in English Courts.

JudgeBread · 30/11/2025 11:16

Mate if your relationship has reached the point where it's reminiscent of a fucking Jeremy Kyle episode it's already well, well over.

BillieWiper · 30/11/2025 11:22

If he's definitely chucked why waste the money on it. They're not especially accurate.

He's just doing or saying anything he can to try and win you back. But he's shown he won't change.

He thinks he'll just pass this crappy test and you'll come running back to him.

I wouldn't even entertain it.

Twelvetimes · 30/11/2025 14:06

But regardless I really do want the detector to be done - the outcome being good or bad wouldn’t matter, I just need to know all the facts. Do you know what I mean? I fucking hate not knowing and I need to know.

But a lie detector isn't going to give you access to the facts, for the reasons given above. They aren't accurate so you still won't know if he's lying.

Sassylovesbooks · 30/11/2025 15:07

I don't think polygraphs are used here in the UK (if they are then it's seldom and in niche situations). They aren't also particularly reliable and can be 'beaten'. Honestly, I don't think you will ever find out the truth from your husband, and you are wasting energy in trying. At this stage your relationship is well and truly over, with no going back. You know your husband is a liar, a cheat and on top is using prostitutes. Instead of focusing on finding the truth, channel that anger into seeking legal advice and getting the best settlement you can for your children and yourself.

fishingfor · 06/12/2025 12:25

Polygraphs have around a 60% chance of being accurate, not much better than mere chance.

JudgeBreads · 06/12/2025 12:58

What’s your fixation with a polygraph op? You’re married to a piece of shit, you don’t need a blood pressure cuff with graph paper to tell you that.

I know that, hence why we’ve separated. There would be no reconciliation regardless of which way the results went, because even what I do know for definite is more than enough to not want to be with him again.
I possibly do have a fixation on wanting to know the full truth, and I honestly don’t see what is so wrong with that.
I was looking for advice from people who had used a polygraph test or from people who could help me come up with the right questions, but it seems I came looking in the wrong place.

Stupidleaves · 06/12/2025 16:10

There's nothing wrong with wanting to know the full truth, OP. The problem is that lie detectors aren't magic. You won't be able to be sure no matter how clever the questions are. I'm convinced I could fail a lie detector test even if I was being absolutely truthful.

There’s nothing at all wrong with wanting to know the full truth. I think that’s natural, even though you’re separating. Posters are just letting you know that a lie detector test isn’t guaranteed to give you the truth, so isn’t worthwhile.
