My sister is dating a sex offender

Am I wrong for not wanting anything to do with my sister since she’s been dating a sex offender.
So she starts dating this guy turns out 2 years prior to meeting him he was accused and admitted to sexually assaulting someone in his house whilst they were resting after not feeling well. It was a house party and the girl was friend of his stepdaughter. He pleased guilty and two years after the assault and 6 months after meeting my sister went to prison got 3 years.
I have refused to have anything to do with her since I found out what he done. He claims he was drunk and had blacked out. I won’t have it. He is now out of prison and they are now living together. I’m just looking for peoples views wondering if I’m wrong for not being ok with it just want peoples views please

I’m afraid she made her choice had long enough to think about it in my opinion and see what’s right

OK, but she may not have calculated the risk to herself. Hopefully she'll realise one day and find a safe way to leave him.

No but I have twin 15 year old girls. The girl was 22 who he assaulted not that the age matters just saying.

Of course the age matters a pedophile is way worse but yeah its not like he's much better

Personally I wouldn't go no contact with her in case she needs to escape in the future.

She doesn't need to come to you but you can ring the police or do something that could save her

Well, my mom's fiance assaulted me when I was on crutches. He broke a window to get into the house but I was out back and thought home invasion.

Some guys try to get you drugged or drunk or out where there's no other people around like hey, I'll give you a ride home and they use force.

I would go no contact as long as she's seeing him. Her choices have consequences and you have teen girls. She is no longer a safe person due to her choice to be with a sex offender. Acting like it's no big deal is enabling her choice. It is a big deal.

Thank you for your reply x

We all know his excuses are just that. But he sounds like someone used to manipulating women.. for that reason id stay in touch with her.

Open door policy, with clear understanding its sister time, her BF isnt welcome. So when she needs to flee him she had a path

Unfortunately it won’t be to my home!

Well she does actually

She has to state this; she will probably lose her job.

usedtobeaylis · 30/11/2025 19:42

She's made a terrible, terrible choice and I don't blame you at all, I think a lot of people would have the same response. Any kind of tacit endorsement and it's like he's been welcomed into he family.

I'm close to my sister and I don't know if I could cut her off completely if it was her, I might let her know that I would be there when she came to her senses or was ever in danger but I really don't know. I don't think I could get over it.

He assaulted his stepdaughter's friend when she was unwell. Some of the predators I've encountered wait until their target is ill or injured and more vulnerable.

I hope your sister doesn't have kids. If she does, let them know you will get them to safety if they need it.

As for her, no, I wouldn't have anything to do with her. She chooses to date a sexual predator, she can deal with the fallout of her very stupid choice.

You need to be firm in refusing to see him, but your sister is at risk and some contact with her family could be a lifeline in future.

Sassylovesbooks · 30/11/2025 19:34

I agree with your stance. I don't have siblings, but if I did, this would be a reason to have no contact with them. I'd feel no guilt in doing so either. Your sister has likely been spun a sod story, that she's swallowed. All I can say is that she must have a very low self-esteem, to think this man is all she's worth.

SwordToFlamethrower · 30/11/2025 19:34

This is utterly horrifying! Your sister is NOT safe.

I don’t quite follow the timeline in the OP. Did this all happen a few years ago and he’s out of prison now? What do you feel has brought it up for you tonight?

Yes been out 6 months now. He only served a year and half. It just plays on my mind a lot.

to be honest it was the icing on the cake. I won’t be keeping in touch been 2 years now but plays on my mind that I think I might be wrong even though I know deep down I need to go with my gut. I feel ashamed she’s with him

You are not wrong. Women get involved with sex offenders all the time—she may or may not have been innocent and naive once but she may well end up being his accomplice. Rose West? There are many who eagerly assisted their boyfriends to commit crimes.

I'd put my life on it that he has similar previous convictions if he got YEARS in jail for digital penetration.

And what you read in the papers will only scratch the surface of what he actually did. They can't usually print graphic details.

Flup68 · 30/11/2025 19:25

I know right!!!

I went to prison in my twenties for growing weed. It's well known how sex offenders have to be segregated for their protection, but I think it's less well known the levels of distrust general population prisoners have towards them. They're not considered criminals inside, they're considered to be perverted, and unpredictable and untrustworthy. There's no rehabilitation for that, it's a complex mental health issue at the end of the day. If prisoners won't tolerate them, why would you?

Dweetfidilove · 30/11/2025 19:23

There's precious little that would cause me to abandon a sibling, but this is one such instance.
She could find me again after the relationship is dead, but I couldn't be around her while she's actively engaged in this.

Flup68 · 30/11/2025 19:23

He used his hands to penetrate 🤢

Erm, blokes who are blackout drunk generally can't get it up!

(I know it doesn't technically say if his penis was involved in this offence but just saying)

CinnamonBuns67 · 30/11/2025 19:20

No I'd not accociate with a sex offender and I'd not want to accociate with someone who chooses to be friends with or in a relationship with a sex offender. Yanbu.
