To want to tell my Stepsister her Dad is a cheating scumbag?

Obviously I'm not going to! But I'm just so angry at the moment I keep having to remind myself that it's possibly just me being pregnant and hormonal. Or not. I really don't know right now.

Backstory: My parents split when I was eight. The hostility was pretty thinly veiled at times, but they've managed to be civil to each other, despite both blaming each other for it. They were as bad as each other in terms of what went wrong, but it was my Mum who finally left. She's always been very "tough" and never let the three of us see how much she was hurting throughout the proceedings, though I was obviously a little too young to have been able to pick up on it in any case. Basically, much as I have issues with her parenting style in some areas (she's a bit of a control freak) she's always been this rock, and I can't help but admire her for that.

She and my 'step-dad' married when I was eleven. He had two children from a previous marriage, but they were in their late teens/early twenties so we only saw them occasionally. His son lived with his mum and his daughter (who was the eldest) was in her own place, and now has three kids of her own. He provided a lot of stability for my mum, who was actually being stalked at the time they met (the police stopped that guy but could only ever caution him as he hadn't physically harmed her) and they seemed to be happy. A few years ago they (and my younger brother and sister) moved to the other side of the country to a lovely big house with a gorgeous garden.

It came out last year that he'd been having an affair for months with two other women. The lies upon lies were pretty bad, and for a while it was touch and go, but he seemed genuinely contrite, and my mum gave him a second chance. He promised to change etc., etc.. My sister reports that they continued to have a lot of arguments though, and I've had numerous calls from my mum where one week she was fine, the next it wasn't so good - for her, the loss of trust was a big deal. She said to me at the time that she couldn't believe that after all she'd been through she didn't think this could happen to her.

Well, last week it turned out that the affair with one woman hadn't stopped, and their relationship is officially over. I spoke to my mum on the phone yesterday, and at one point she was in tears. The only other time I've known her cry (apart from when this first started last year) was when my Grandad, who she was incredibly close to, died. That made me pretty mad in itself, that he could do that to her, when she's normally so "strong". She was apologising to me for it, too!

Yesterday though, she also said that he's told his two brothers that he and my mum are separating. From the way he reported it, I would imagine that he's just said 'it's over'. But I don't think he's told his children yet, and when he does, I don't think he's going to tell them about the affairs. Apparently his last marriage ended because of an affair, and they weren't told about that either . (I know, hindsight, eh?)

For various reasons, he and my Mum are going to still be living together for at least the next six months (my brother has SEN and is at college, so needs stability, for one), so I can easily see him passing it all off as a relationship breakdown. I know it's utterly irrational, but part of me really wants to phone up his family and tell them what he's done, and how I hope they're proud that he's managed to break my mum in a way that nothing else could.

So how unspeakably U is that of me? Please be a little gentle, I am 36wks preggers and so pretty hormonal!

No, enough people have already been hurt. Don't add to it - they'll find out in the end anyway.

you sound protective of someone you love thats NU

but to tell your step sister.brother yes that would be... if your mother wants that allow her to do that if not then accept her wishes and moan here

My exH cheated on me often basically from the very start. He never told his family that was why we split up and made it all out to be my fault. His family didnt speak to me for ages until his dad found a letter from my granda (granda is very religious and doesnt believe in divorce so exH had tried to get him to talk to me and take him back. My granda said i was better off without him). They started talking to me after that.

What i supose im trying to say is the truth will come out eventually

Greensleeves · 21/06/2010 13:03

it isn't your stepsister's fault though, is it?

lashing out at others will make you feel worse in the long run

TottWriter · 21/06/2010 13:07

I wouldn't actually call her for that reason BAFE, but it just stings that throughout this he's not suffered at all. Now that it's over he seems quite happy to carry on living there, and probably sees it as free reign to carry on seeing this other woman for the sex and have my mum around to carry on doing the housework and be there for a conversation. (He told my mum that the affair was 'only' about the sex, so obviously it wasn't that bad. )

She isn't going to live with him forever, of course, but right now it just feels like he's gotten off scott-free and there isn't even the justice of his family knowing what a scumbag he is.

WHlist you don't have to bring it up straight, you could always assume they know. Not like your SD has told you that he is not telling them the reason they have split...

so that next time you are speaking to them and it comes up in conversation you can just just make some throwaway remark about how gutted your mum is, that you really thought that after he had said it's over with the other women it really would be, etc etc, didn't they think... and see what they say.

I'm sure if you think about it now you will be able to come up with a couple of perfect lines to drop into the conversation.

and if your mum or sd ever say anything about you saying anything, just say that they had never asked you to keep it secret, if you had been told about break up and reason, then it is perfectly reasonable to expect that they treated all step-children the same and told you all the same thing.

sorry to hear that your mum is hurting, must be difficult when there is not much you can do about the situation.

You're not unreasonable to want the world to know what your mother's husband has done to her and how much he's hurt her. But is it the right thing to do? Does your mum even want you to? I certainly don't think it is the right thing for it to come from you. If your mother is asked, or even I suppose if you are asked, there would be no reason for you to lie about it.

If you are asked.

But to phone up people in the hope they will, what? Hate him? Think he's a bastard? It might make you feel better in the short term if they react as you want them to. But what if they don't care? What if it doesn't bother them what he did? What if they told you some things about your mum that he's told them (you have no idea what he's said to them). That has the potential to hurt you.

You're angry. You want everyone to think he's a bastard and to be angry with him. That's understandable. But I think if you go round phoning people up to tell them what he did, it may very well end badly for you.

You mustn't blame his family or hope they're proud of him. He is his own person and a total tool, but dont let your fierce protective instinct for your mum make you any enemies.

FWIW I dont think you'd be wrong to break the news, it just depends how you do it. If the marriage is over, there's no harm in telling them gently. They will probably be mad and ashamed of him without any help from you!
My dad broke my mum recently in much the same way you describe, yet all of his family is mortified that he's this and feel so guilty. They certainly aren't proud of him.
