Fiance slept with a prostitute

@Adviceneededrewedding He said the girl took his trousers down put on condom and they had sex for 30 seconds then he said no I can’t do this and ran out of the house and made his way home.

So he didn't sleep with a prostitute. Sleeping with a prostitute would be very uncommon as that would be overnight.

He had sex with a prostitute for 30 seconds, then left because he felt unhappy about what he was doing.

You would have more to be concerned about if he had no issues with what he had done, and if he had no issues with it, he would not have told you.

Two quick thoughts, sorry if already said.
has he confessed because his friend will tell her so he’s got in first?
Sexual health clinic check up .

He sure remembers a lot considering he was paralytic drunk, where did he go after he walked out, has he bothered getting an sti check.

He’s treating you like an idiot.

ARE you an idiot?

This man should already be an Ex Fiance.

I just read your DP's account of what happened to my DP. He laughed and said "Uh-huh."

I am sorry this has happened, OP, but you know what to do. This man is lying to you. His behaviour is revolting. Get him out of your life.

The only part of what he said I would believe is that he slept with this one that night. The rest could well be lies, may well have done it before, is just grim, I'd move on.

Please don’t get married. There is a better life out there for you.

He sounds an idiot and was persauded that it was okay to pay to rape a woman. He seems to have repented of this folly. I'd be having words with work colleague who thinks it's okay to pay to rape someone.
Would reconsider marrying him OP, not only for the folly and, more, the broken faith, but also because he's an easily led idiot with no proper moral compass that doesn't stand up to someond saying 'everyone does it' and 'this is normal'. Though standing up against such ideas is difficult, I know.
But paying to rape is about as low as you can get (because paying to rape a woman is what prostitution is).

This is probably more like what really happened.

He went on a work night out, shagged someone and was seen. He’s now worried someone will tell you and has come up with a bullshit story about a brothel to try and convince you it was a mistake.

Don’t be the idiot who falls for it.

Presumably his lady callers all wear very high heels, fishnet tights, shiny black mini skirts, low cut tops, lots of badly applied makeup, a messy up do and are ostentatiously chewing gum?

Why did he even tell you?

You’d be an absolute idiot to even think about forgiving this. Decent men don’t behave like this. Ever. Drunkenness is no excuse.

Throw him away and keep your dignity intact.

He’s shown you what a weak specimen of a man he is.

Drinking to excess is a repulsive trait and a gateway to excusing himself in future for more misdemeanours! ‘I drank so much I suddenly found my cock in a girls mouth but you know I would never do that, it’s the drink that made me do it!’

‘Broke down crying’ - yuck! What a pathetic wet wipe! He did this to manipulate you into feeling sorry for him so that he can play the victim and blame it on the booze and his friend setting him up.

He is a disgusting, weak willed sorry excuse for a man and if you don’t break off the relationship, then more fool you because the way that lies ahead is more disgusting behaviour and more misery for you.

Like everyone has already said do not marry this man. Sounds like he wants to tell you first before anyone else will. Good luck OP.

I highly doubt he was that reluctant, sorry.

This, sadly. There is always more.

For a start, he would have had to pay up front. Is he saying he got out his wallet, counted out the money, allowed her to undress him, put a condom on his convenient erection and accidentally had sex but then thought 'oh no, my fiancee won't approve.' ?

I'm sorry but I doubt it.

If he genuinely ended up somewhere he didn’t want to be (unlikely,) he could have just walked out.

"Paralytic"... but remembered all of this info and still managed to get an erection and have sex for "30 secs"🤔

Everyone who cheats "have never cheated before" their first time, too.

Don't marry him.

Get rid, you deserve better.

Has he got a stag do planned? Amsterdam by any chance?

Seriously walk away now, the anxiety and heartache staying with him will bring will far out way some upset and awkward conversations right now.

He can spin it anyway he likes, he’s disgusting. Set yourself free.

It's pathetic that he tried to minimise it, like he was forced into it.

The silly bastard. The whole speil about his colleague telling him he was going to meet a business contact. How he was 'confused' when it was a fucking whore house?!

He's a lying twat and of course you should dump him. And get tested.

I wouldn't go near a man who sleeps with prossies with someone else's barge pole.

Who paid? The generous, conniving colleague or Mr I-was-so-shocked-I-couldn't-even-undo-my-own-trousers? Does he plan to report this assault to the police and probably work (as colleague has got him drunk and aided an assault)?

Dump him and then make an appointment to get checked at a GU clinic, goodness only knows what risk he’s been exposed to.
