Your (hopefully by now ex) fiance is a horrible skank (a great word that enrages the right people) who cannot be trusted. Not just one night of cheating with a stranger that you know about, two per your updates (that you know about).
He chose to get so munted he allowed a barely dressed slapper to humiliate him in public. Then he chose to let her smear her fanny on his face.
His friends are beyond pathetic and it's a massived flag that they're people he wants to spend time with.
He's either such a filthy grub he enjoyed some slapper's fanny juice smeared on his face (and if he'd even tried to turn his head away you'd have told us - let's be real he got a good mouthful - enjoy that thought next time he's putting his mouth near you 😣) or he's such a pitiful wanker he lets his grub friends direct his behaviour.
Imagine you went out with your mates and let some sleazebag wipe his cock all over your mouth, and you allowed him to bare your arse and let him beat you in front of a cheering crowd. You would, rightfully, be called every filthy name under the sun and summarily dumped.
So if you marry him, you will get precisely what you deserve. You will NEVER be able to trust him, obviously, and he will know he can do as he pleases and this will be your life. Forever. It is incredibly hard to change even one aspect of our character and we have to want to do it and be committed to it. Why would he bother? He enjoys being a gross pig and knows all he'll get from you is a bit of a tearful tantrum and then it's back to slappers-are-us whenever he feels like it.
This is his behaviour BEFORE he has you locked into marriage with vulnerable kids in the mix.
This is who he is. Accept this.
Are you going to marry a gross skank of man who enjoys a slapper's fanny smear in front of a cheering crowd? Are you going to choose a few years of humiliating behaviour, deep sadness, growing anger and finally divorcing him having wasted years of your life on this sad prick?
Or are you going to choose to have dignity and respect and accept that actually men who behave like this are by far in the minority, and you deserve better.
Those are your options. Pick one.
PS some women have very low standards and leap in to try to lower other women's standards. It's much the same behaviour as you see in junkies or people with horrible lives who have made poor choices, misery loves company and they hate to think so many women have escaped from the misery of living with a grubby sleazebag of a man and they've popped up here to try (and fail) to minimise the man you (apparently) still kiss allowing a slapper to smear her fanny on his face to a cheering croowd.
They're the ones who pretend to be offended by calling a slapper a slapper and a skank a skank too 😅😂 Or, even better, manage to manufacture some actual offence.
Being a mealy mouthed pearl clutcher (whilst almost always minimising and defending what is actually horrifying, the behaviour) is standard on this site though and I will laugh a merry laugh at anyone pretending to be fauxraged about my terminology. Don't want to be called a skank, don't act like one.d
