My girlfriend wants me to take a lie detector.. should I do it?

We’ve been together almost 2 years, but it’s been on and off lately. She’s always had trust issues that aren’t really about me, but after our last breakup she asked if I’d been speaking to anyone else. I told her honestly that I’d signed up to a dating site for a few days and chatted to some people, nothing more. She ended things, said it was over for good.
A few weeks later, she got back in touch. Now her anxiety is through the roof, she’s constantly looking for reassurance, and she says the only way to “move forward” is if I take a lie detector to prove I told the truth. I’ve told her I think it’s unhealthy and I don’t want to do it, but she keeps pushing.
I do care about her, but this is stressing me out and I’m starting to wonder if this relationship is even worth it. Should I take the test just to shut her up, or is this a big red flag?

Even if you did a lie detector test and passed it, there’d be something else that comes up because her trust issues are to do with her, it will only soothe her anxiety for a moment. She’s not ready for a relationship and unless you want to carry on an off-on relationship while being accused of everything under the sun you need to walk away.

Sodthesystem · 14/08/2025 14:57

No, the relationship is over. Tell her to never contact you again. She sounds like a psycho.

Assuming of course you haven't cheated on her in the past.

But either way, it's done now so why on earth do you need to jump through more hoops?

Delphiniumandlupins · 14/08/2025 14:59

A lie detector test won't help her. She'll think you cheated it or that you have been talking to other people more recently. This is unhealthy and not making either of you happy. Move on.

“After the last breakup” 🚩

BCBird · 14/08/2025 15:50

No way would I do.a test. She is not in a good place to.have a relationship.

YodasHairyButt · 14/08/2025 15:50

Run and don’t look back.

Are you mates with Jeremy Kyle?

TheGrimSmile · 14/08/2025 15:55

Time to move on. Your life will be hell if you stay with this person.

gamerchick · 14/08/2025 16:02

Relationship doesn't work OP. Tell her to do some work on herself before getting in another relationship. You could do one and it'll be something you'll end up doing again when she can't manage her anxiety.

It doesn't work..let her go.

Thatsalineallright · 14/08/2025 17:11

How bizarre. Why would you want to be with a woman like that? I really struggle to muster sympathy for people stuck in toxic relationships when they've clearly walked into them with eyes wide open.

80s · 14/08/2025 17:21

I can just about imagine getting back with someone after one breakup, but if they then broke up with me a second time I'd be out anyway. Why did you go back for more, do you think?

SavageTomato · 14/08/2025 20:05

Why do you feel you have to stick around and help fix her? Not your problem to deal with and you can't fix her anyway. She just likes yanking your chain. Drop that rope and fuck her off. Permanently.

chipsandpeas · 14/08/2025 20:14

id do the test then end the relationship

QuietLifeNoDrama · 14/08/2025 20:28

Relationships should not be this difficult this early on. If you do this test now how long till you need to prove yourself again.

Frostywinterwoods · 14/08/2025 22:32

You joined a dating agency not long after splitting. I think that says it all.

What does she think you are lying about? If she doesn’t trust you the relationship is basically over.

You can’t placate an anxious person, anxiety only wants to be fed.

Time to move on. This isn't going to get better and you will also feel that she is looking over your shoulder all the time.

I would do the test and then end it. But I can be petty

Me too!!

Block and delete the coercive control freak.

https://freedomprogramme.co.uk/online.php

Do the freedom programme and learn about spotting red flags in future relationships and partners. This woman is dangerous so you need to stay well away from her, if you feel you're in physical danger then report her to the police.

Motherofalittledragon · 15/08/2025 18:32

How many break ups have there been? No it’s ended and keep it that way 🚩🚩🚩

LearnSomeSocialSkills · 15/08/2025 18:33

Firstly they are not 100% accurate, according to info they are only around 80%.
Secondly, where does she propose you book in to do this? They cost £450-£500.
Thirdly -do you need your head examining?!
She is never going to trust you, no matter what the outcome of the test. If you ‘pass’ this one then there will be some other issue/occasion she questions.
Move on. Life’s too short for this shit.

End the relationship and recommend she gets therapy for her issues before entering into another relationship.

This.

unless of course you have been a massive flirt or given her reason not to trust you. If you have, then own up £ stop messing with her head. Either way, you need to end it & both move on separately.

AgnesX · 15/08/2025 18:36

Where do you even get such things (not that they're even reliable). I'm not sure who's more bonkers to even consider it - her or you.

Short answer: cut your losses and part company.

Onelifeonly · 15/08/2025 18:36

Even if you did and passed, she would still need another one to be done a few days / weeks / months later. It's a hiding to nothing.

What is she, 15? Unless she is, I would give her a wide berth.

I’m gonna go ahead and say he should give any 15 year old a wide berth…. 😳
