To keep quiet about alleged DV?

[Hoppinggreen]

A lady I know reasonably well came up to me t work today and asked how I know B( bloke) because he has asked her out. He doesn't work with us but from FB she could see I was friends with him.
I actually know him because a very good friend of mine is currently divorcing him so I have got all sorts of " dirt" on him that I won't be dishing as I know the source may not be entirely reliable. However, I do believe a lot of what my friend has told me, including a couple of incidents of DV during the break up.
Now I actually like B and I know that my close friend wasn't entirely blameless in the break up (affair) although I know there is no excuse for DV. I have known B for about 20 years and have socialised with him. I think they would be a great couple and have no issue with my friends ex moving on at all so that's not it. I definitely won't be mentioning this to my friend, she knows he is dating again, so is she and their relationship is quite amicable.
Now my dilemma is what if Nything to tell the lady who he has asked out. I don't want to get involved and I don't want to tell her anything potentially untrue but I DO believe this man was violent to his wife at least twice. ( seen bruises etc) It was many years ago and they actually put it behind them and made another go of their marriage until recently when the split up again - for good this time.
The other thing is that I know the lady who asked me has been a victim of DV before, which means I doubt she would never go out with a man with a history of it.
I have managed to not say much so far but she keeps asking about him. My Husband says keep out - should I?

Have you ever been in a DV situation OP?

No I haven't.
I have been subject to mental abuse briefly when I was in my early 20's but never DV.
Why is it relevant though?

I'd tell her what you KNOW but I'd say, there's always two sides to a story. As she keeps asking, if you just went upto her and told her I think you'd be out of line. But not as she's asking.

I was just wondering to be honest. If you met someone (

Before DH who had a history of MA and a friend of yours knew would you have wanted them to tell you knowing you had been there before?

Of course you should tell her, and then it is up to her what she does with the information. Someone who has once been a victim of abuse, is more vulnerable to it again, so she might well be wise to keep clear. Don't overdramatise, just tell her plainly what you know, in context (eg years ago, they got past it etc). She is a grown woman and can then make a grown up decision.

NOT telling OTOH could make you complicit in covering up a man's violent past and that leading to a violent future. Do also tell her that you like B and think he has a lot of positives (say what they are).
