Would you want to know of your husbands affair?

[Allmond]

When I was younger and super naive (about 10 years ago I am 30 now) I was in an abusive relationship with an older man, for 5 years.
He seriously affected my mental health and made me believe I was crazy. He psychologically and emotionally tortured me, and stalked me for years after I ended the relationship. He still attempts contact with me but I do not reply.

I was led to believe he and his wife were divorced.

I have recently unintentionally found out he is still with his wife and was never separated/divorced from her in the first place.
Now everything makes sense. He lived a double life for all those years. He worked away from home a lot which is how he got away with it for so long (his wife also worked away occasionally).

Now, I feel like if I was his wife I would want to know how much of a nasty character raging psychopath he is, but because I am still traumatised by it I would rather forget that relationship ever happened and avoid his potential retaliation.
At the time time, I’m thinking surely she must know how evil her husband is and be abused by him too?

Aibu for not saying anything?

For the sake of your own physical and mental health, I'd advise not to tell her. Leave Pandora's box alone. She'll be ignoring red flags, so let her. You are putting yourself at risk of him again if you tell her x

I would want to know.

Don’t expect the wife to thank you though. She might even be hostile to you and blame you, or not believe you.

I actually have no idea if I’d want to know or not but I’m thinking I wouldn’t.

Op 3 cats is right
Don’t get dragged back into this mess
It’s not yours to solve and the wife probably knows he is a douche

It’s not really the same question as your thread title, the situation is too complicated and I 100% wouldn’t get involved.
