To be upset about DH reaction to ex pregnancy

[PickAPair]

Been with DH 10 years.

He has one big ex who was still in regular/drunken contact when we got together. Caused a lot of issues at start. She is very beautiful and DH worshipped her. V toxic off/on relationship but I told him if he wanted to be with me he had to stop contact, which he did.

He says she is "mad" "destructive" , she was violent, got personality disorder etc.

She has not come up in conversation for years. Now she is pregnant and DH found out. He told me this saying stuff like "the poor baby, I can't believe it, she will be the worst mum in the world, probably neglect her child" and he seems quite upset about it

I said "you haven't seen her for 8 years. give the poor girl a break"

And he is mad at me. Saying I'm insensitive. She is a perpetrator and I'm implying she might have changed and I don't know what I'm talking about

I just feel miffed he was upset about it. But also he talks like he knows her when it's been a decade.

Should I just have kept my mouth shut?

He's been hung up on her when you met. Probably some jealously and mixed feelings.

What could you do anyway? Yeah DH, I'm sure she'll be an awful mum and batter her baby? I'll get the police around now?

Yabu, having come out of an emotionally and low level physical abusive relationship 15 years ago I would still pity any child my ex had. For me there is a weird dynamic of feeling guilty of not stopping that person hurting others.

It's a strange illogical feeling as the abuser is the only one guilty. I would recommend you apologies because I think he is correct if it was a woman friend would you have said the same thing?

He seems to be very invested in a child that isn't even his..........is it ?
