Is my partner lying to me and potentially cheating?

So this is an odd one, but I think my partner has been cheating lately. Every time he tells me a story it's flawed and makes no sense.

There are many stories but the most recent one I'll start with. He claims he went out for food with a work colleague at The Railway pub in Streatham.

He showed me a photo, nothing suspicious here. Then I checked the menu, the dish he is eating isn't even from the Railway menu, and the table is different in the photos.

Also the plates don't match social media.

I know this is petty but I have many more examples, I'm wondering if I'm losing my mind here. Signed up for second thoughts as I don't know where to turn

Ok so around Christmas he was in London for a work party, sent me some photos, claimed to be out all night with his colleagues and bosses. I am fine with that, the problem is it cannot be true I think

I created a time map and it became impossible to be out all night. He had to be back in the hotel multiple times, for a total of 3.5 hours. I used the photos sent to me and times and distances between locations to prove this.

But he claimed to be out all night which was impossible. Like he claimed to go to Borough market for food with his boss and colleagues, which I found to be impossible by piecing all the puzzle pieces together.

Like I said the absolute total time outside hotel by photos and distances would be maximum 3.5 hours

You did what now 😳.
Your behaviour sounds menacing and I wouldn't tolerate any of this at all.

Your first post made me wonder if you'd been cheated on or was paranoid and controlling, but this 😳?

Whichever it is, just be single and get some help. For yourself and the next person you'll be with.

@JanetCompost

I understand completely where you are. I know you need answers. I know you have to know you're not crazy. The damage done to you has sent you well past seeing the bigger picture and what he's turned you in too.

All I can tell you is that he's a liar. This many inconsistencies don't happen in normal relationships, whether friendship, or romantic, when there is nothing to cover up.

What he's lying about, who knows. But take a moment, you've worked out that he is lying about his Christmas night out. Was he cheating? Gambling? Secret child? Even something criminal? Who knows. But he lied about his whereabouts, to his romantic partner. You know that much.

Your brain is doubling back on itself with what you are telling it cannot be true, being processed alongside his gaslighting "truth" plus a good measure that you are deranged and paranoid. This is really quite dangerous for your mental health.

You need to satisfy your brain. You need to know you aren't mad, for your own sanity, and ability to trust yourself again.

Phone the pub. Speak to a woman. Be honest. Tell her you suspect your partner of having an affair and it's consuming you. Tell her about the plates and ask if she has them. Jeez, endless women have phoned a hotel to "catch" their husband mid affair. Even turned up trying to catch them. So who gives a shit, you're phoning the pub. If she gives you the information you need to prove he was lying, then it doesn't matter finding out the lie.

Sending love, and strength. You will get through this and at some point you will find what you need to know you aren't mad. He's made you this way. From personal experience, I almost didn't care what he'd done, my peace came with the irrefutable evidence that he'd done it, and I wasn't some broken "stalking nutjob". I was right, and sane, and true, and genuine all along.

You've got this x

BuckChuckets · 12/10/2025 18:35

Yikes, I hope someone who knows OP's partner sees this and realises who's involved. So they can tell him, and he can escape!

Livpool · 12/10/2025 18:48

OP - end the relationship and get into therapy. You are stalking this man, your partner. If DH was questioning me and plotting my whereabouts I would go to the police

Janet, I don't mean this unkindly, but you are abusing your partner and you need to stop. Now.

If you are being honest that this man has done nothing wrong other than these three occasions when you have analysed his movements/actions bizarrely and intrusively, and found what you claim are inconsistencies, then it is you who is in the wrong, wholeheartedly. It is not normal to do this to another person - it's insanely controlling, stalking behaviour.

I have been on the receiving end of this kind of abuse and it's horrendous, it does extreme harm to your mental health. And yes, I did end up lying about my actions and whereabouts sometimes, not because I was cheating, but just out of extreme resentment that my actions were being subjected to this degrading level of scrutiny, and a desire for normal human freedoms.

And yes I have been lied to and cheated on as well, and while that is not nice, it doesn't even begin to justify this kind of dehumanising behaviour.

I am going to assume you are doing it because you are unwell, not because you are a malicious cruel person. But the impact on your partner will be cruel and damaging, regardless.

You need to seek immediate help. And not be in a relationship currently if you are unable to restrain yourself from this sort of conduct.

And what you feel for him isn't love, or at least not a healthy version (though you may believe it is). It's paranoid obsession and a form of ownership.

I agree. Even if he was cheating or hiding things - this behaviour is inexcusable. If you believe that this isn’t the right person for you then leave. You should not subject someone to investigations, interrogations and diagrams and certainly not offering to pay a stranger on the internet to visit the venue to try and further disprove anything. Even if OP was being cheated on, her behaviour right now is not only problematic but a serious sign of MH issues. The people here saying this is completely normal are bonkers.

KiwiFall · 12/10/2025 19:06

I sorry I’m not sure how much of this I believe. You seem to be very intense in your trying to catch him out. This isn’t normal or healthy. Before the Christmas incident were you always like this? Have you been like this about other boyfriends? You have several choices:

  1. Go to this pub yourself and show a picture say you would like this dish as a friend had it and it was apparently so good you wanted to try it
  2. Speak to him but would you believe what he says? I doubt it as you are so far down the rabbit hole at this point
  3. Trust him (which I don’t think you can do given your obsession with catching him out)
  4. Hire a private detective (again if he is innocent would you believe it and never start up this behaviour)
  5. Walk away

This is an extremely irresponsible post. The OP needs help, not justification for her highly erratic behaviour, which presumably you haven't even read

Phoning a pub is crazy. Ok.

Best to just continue questioning if anything around you is real, and that you must be the problem.

You have no idea what he's done to her to get her in this state. None. And she can't see it because she's in it.

Me? I spent 5 years being abused by a narcissist. Faking where he was. Making me think my own mind couldn't be trusted. Took me to the doctors to get medication for my "mental issues."

Until the day I phoned the airport and claimed I needed a receipt for my work expenses, for my airport car parking. They found my registration and forwarded the details to me. I'd arrived on the Friday and left on the Sunday apparently.

He'd lied that he was "up North" for a wedding, and when I called it was an international ring tone. I called back immediately and it went straight to voicemail. He blocked my number until Sunday evening. Came home, "what the fuck is wrong with you, trying to hassle me when all I want to do is have one weekend at my mates wedding, of course I blocked you, you control freak. International ring tone? I've heard it all now, you've actually gone mad. You need a doctor."

It took me two years to pluck up the courage to phone the airport. Actually I phoned 3. Heathrow first. Gatwick second. It was the third, Stansted, that he flew from. A quick getaway with whatever he was sticking his dick in that month.

And just like that, it was done. I wasn't mad. I didn't need fucking tablets. I told him. His response? How dare the airport give out that information. He would be making a complaint to the highest level.

I threw him out that night. Looking back I can't believe how much I endured and how serious it was. It took two years and all my strength to phone the airport. And I truly believe it saved my life.

Phone the fucking pub.

Mealy82 · 12/10/2025 20:11

Parkxyz · 12/10/2025 18:59

I had a friend who ended up getting sectioned, who was displaying similar behaviour to the OP, so it's at least plausible. He became paranoid, then came up with absurd theories as a result of the paranoia and then found 'evidence' that proved the theories were correct. For example, he started believing that Stephen Fry was following him, then found some pizza in a place where it wasn't meant to be, and that was the proof that he needed that Stephen Fry was following him, as Fry must have put it there. No amount of logic could convince him otherwise.

What the OP needs is help - not people advising her to phone a pub to find out if her theory about plates is true even though it makes no sense and has already been proven by other posters to be incorrect anyway.

That was your experience - I and others have our own experiences. So you think OP is being rational by plotting a timeline of whether her partner could have been where he said in London?

My DH is going to Germany with friends next week -
I won’t be checking his photos to check he is where he said he is.

It wouldn't even be that, the equivalent would be you demanding he send you a picture of every single new location he is in, then putting all the pictures on a map of Germany, printing that map out and writing out the times he sent you the pictures on the pictures on the print out, along with 'this proves it was impossible that he spent more than three and a half hours in his hotel' next to the map, and then scanning that in and posting it to strangers on the internet so they can confirm to you that this is proof that he's lying and not that nothing you've done makes any sense

So your experience is that you've never experienced anything like this. Super. What a help.

I was told I needed help. I didn't need help. I was in a state of mental torture at the hands of a terrible human being. No one believed me. I was "crazy" and he was just lovely, even standing by me through all of my "issues," what a guy.

Noone remotely clocked on that I didn't have these "issues" before he was on the scene. Just what a lovely man he was. And how I was not well. Funnily enough, I haven't had these issues since either, it's like they went away. What a riddle, eh.

You don't get it until you've been in it. You don't realise it when you're in it. And it really doesn't help to be told you're crazy. It's your brain trying to help you prove that you can believe what all your senses are showing you. It's horrible.

Thewookiemustgo · 12/10/2025 10:30

OP I don’t think this thread will be doing you any good.
You wanted reassurance that your ‘evidence’ meant that you can get an ‘answer’ to living in a sliding doors and shifting sands situation.
Nobody knows the answer to any of this except your partner, but all we have become is an echo chamber of the conflicting messages you are receiving from your lived reality: “Everything is ok really and you are just being paranoid and he is a victim of your stalking”
versus:
“Why is he being vague and saying things/ recounting his activities in ways which don’t add up? Why is he lying? Is he even lying or am I paranoid?”
Either way, this is spiralling you down a very painful and confusing hole resulting in real damage to your mental health.
Your mental health and getting support should be the focus. We are describing the water to a drowning woman, she needs some lifelines.
The thread has divided into these two camps, which only serve to mirror the nagging doubts you are trying to quieten in your own head which caused this in the first place.
“He’s cheating/ she’s an abuse victim” or “No, she’s clearly an unhinged stalker” are the two things OP fears most. Her cognitive dissonance, for whatever reason, is off the chart and has left her struggling badly and doing things none of us ever think we would do but in her circumstances we probably would. These behaviours don’t just blow up to this level overnight, it will have been incremental over time, whatever the source or catalyst was.
Whichever is true, the clearest thing of all is that she needs support with her mental health at this point.
With only your best interests at heart I think you need to find some counselling support and to have a long, honest conversation with your partner about your fears and why you suspect him of infidelity.
When you have his answer you either believe him or you don’t. If you don’t, then there is no point carrying on with the relationship, because you will sentence yourself to a life of anxiety and detective work which will end the relationship one way or another anyway.
For whatever reason, trust left the building in this relationship a long time ago and feeling like this is no way to live.
If you have got to the point where only him providing a forensically accurate account of his every move he makes will satisfy you going forward, then this relationship has become toxic for both of you, whether he is abusing you or you are trying to control him.
Have you explored the possibility of relationship OCD? ROCD is a real condition and behaviour like this is common within it.
I really don’t like suggesting this in case you are actually a victim of abuse, but in the absence of abuse, I would look into this instead.
Either way, with no honest communication, you need to get out of this relationship as soon as you can and have some counselling support.
OP’s holy grail quest here is to answer that question, Is he lying or am I stalking a faithful man? which only he can.
Arguing about whether or not he is an abuser or whether OP is stalking an innocent man only adds more fuel to OP’s already raging fire.
Please get some support OP, confide in a trusted family member or friend if you can, don’t be alone in your head with it any more.
Imagine a life where you woke up in the morning free from doubt, suspicion and questioning yourself, him and the whole toxic circus your life appears to be. Imagine a morning where the only question in your head is “What shall I have for breakfast before work?”
That should actually be pretty much the only thing you need to ask yourself when you wake up in the morning in a healthy relationship.

Absolutely fantastic advice (and one of the best responses I’ve ever seen on MN)
