To be worried about stains on my boyfriend’s sofa

You don't need evidence OP.

The fact that you don't trust him and that you are looking for evidence is enough.

This man isn't for you.

He even boasts about cheating.

Perhaps you are not ready for a relationship at the moment.

It could be that you need to have more experience of trustworthy people before thinking seriously about one person again.

And because he openly, repeatedly cheats on women?

That stain could be anything. Anything at all, and there is nothing about it that specifically suggests cheating.

When you are not there he probably sits in the same position, eating stuff, doing stuff with pens, fiddling with mending something that drips oil or WD40, tucking his foot up on the sofa and getting stains from his shoes on it. Maybe you put your own bag down on the sofa and something was stuck to the bottom. Maybe he comes in and puts his shopping or work bag there. Maybe a bat got in and shat on the sofa.

Oh OP you could drive yourself mad with all this. It’s such early days, he has a history of prolific cheating and you are already taking photos of his furniture. Walk away now with sanity in tact!

You can't be with man who has you so paranoid that you're interrogating random stains on his sofa and posting on the internet about it. Stop.

Take what's left of your self respect and leave. You clearly have a very toxic and paranoid future ahead if you stay with him, regardless of if he's cheating or not. Don't do that to yourself.

You think your partners cheating because there are stains on the sofa?!!!

They've been using a non water-based lube by the sounds of it. Mr. Blobby looks oil-based

Cheating... stains... it doesn't sound great.

I'd knock him on the head. I wouldn't be with someone who told me he was a serial cheater. He's just telling you to be prepared for the inevitable.

There are good blokes out there and while you wait for one to pop out of the woodwork, be single for a while and work on yourself and raising your bar.

This is the wisest woman on MN - nay, the whole of Beyoncé’s internet - today.

Ha, hello emotional support twin!

We get on really well in all other ways and he’s the most supportive man I’ve ever known

Maybe, but at only 6 months in anyone can put on a good show

I'd be more bothered about the cheating which he "speaks openly about", doubtless so that when you find out he does it to you too he can claim you've got nothing to complain about because he "was open about what he's like"

YABU for getting into a relationship with a known cheater.

Those stains could be anything 🤷‍♀️ blood, food, drink... literally anything! The bigger issue here is your lack of trust. He has a history of cheating - that's why you think he's untrustworthy. The biggest indicator of future behaviour is past behaviour OP. Why are you dating a bloke with a history of cheating? Especially as you've experienced being cheated on in the past!

In all honesty if it's got to the stage you're sending photos of a stain on his sofa to an Internet forum I think the trust has gone

I think if you’re at the point of inspecting his stains then you need to call it a day. It’s only been 6 months, he’s an open cheater and you both seem too old for these games if you have kids in their 20s.

Find someone you can trust.

He's a serial cheater with a manky sofa - sounds quite the catch. You say you have never been with anyone who hasn't cheated - do you think a self confessed serial cheater is going to be the one to break the streak? Get rid.

Cheats don't just stop being liars and cheats when a new woman rolls around!

He has learned he can have his cake and eat it too. You should dump him for his stanky history of lying and sticking his wibbler in as many woman as he can while making them think they're the only one.

He's gross and you deserve better.

This relationship hasn't got legs to stand on, you are 6 months into a relationship and are taking pictures of his sofa, asking mumsnet what we think it could be. You dont trust the guy, and you have good reason to, he openly admits to being a cheat, you now have it in your mind he is cheating, and so will see things that might/might not be there. Imagine if there were two cups out, your mind would jump to 'did he have someone over' - when the explanation could very well be he had two drinks. You dont trust him - end it.

Sending a pic of the new black marks which could easily be a leaked pen but it’s weird that it’s so close to where the other stain was.

So both could have just been something that was in his pocket which has leaked then?

You've been cheated on by every boyfriend you've ever had, and you've still started another relationship with a man who admits to being a serial cheat?

OP, this is beyond unhealthy. The stains on on the sofa are not the issue here; they're meaningless. The issue is that you are in a relationship in which you're never going to feel even remotely secure. Are you some kind of masochist?

Six months into a relationship you should not have to be worrying about stains on your boyfriend's sofa. If he has a cheating past, why would he be any different now?

was just about to edit and amend, he's cheated before so why even start anything! absolutely stupid IMO

@toomuchfaff 'If your not able to trust someone who hasn't given you reason to distrust them - get help.'

He's given her reason to distrust him, and he openly admits cheating on his exes.
OP should have dumped him upon hearing this, anything else is just signing up for humiliation and misery.

What are you even asking?

Do people think my BF is snagging someone else because a pink stain on the sofa?

Because if that's your ask, I suggest you get help for your obvious trauma and trust issues. Either that or there's FAR more to this scenario.

If he's untrustworthy then leave him

If your not able to trust someone who hasn't given you reason to distrust them - get help.

Could it be the same stain that has turned dark?
