Unintentionally hurt a friend

[LaChatte]

I recently put my foot in it with someone I really like at work (we also socialise outside of work too).
She's been complaining about her waste of space man-child cock-lodging partner for as long as I've known her. Last week she asked DH if he was free to help her move his stuff out of their house. I was surprised and asked her what was happening and she said she though she'd told me that they were splitting up. I reacted by saying congratulations and she started to cry, saying how she was 40 and now a single parent. I tried to comfort her and get her to focus on the positive side of things and she eventually seemed OK.
DH told me later that saying congratulations wasn't the appropriate response (I have form for doing stuff like this but I never intend to hurt anyone and its never until DH tells me after that I understand why it's insensitive).
Anyway I wanted to try and make it up to her, DH says I should probably just leave it as she knows that I don't do these things intentionally, but I can't help thinking about how I've hurt a friend and want to make it better.
Would it be best to follow DH's advice or should I do/say something to friend?

To be honest I am pretty sure that in this case it also does not matter- she was emotional and you said something she KNOWS is true base don what you said. I wonder if you and your husband are not overthinking it a bit in terms of her reaction, I doubt she thinks of it now. If it was me, Id not doubt a long standing friendship over something like that.

I think sometimes it's hard to realise your part in the shitshow. You wanna think that you're a strong person and this bad thing just happened cos you were unlucky.

I remember feeling anger at a friend who asked me why did I put up with him. I was bit shocked. The "script" was that she'd join me slagging him off,but she turned it back on to me. I remember feeling shocked,initially.

But that was 17 years ago. 16 years ago I realised it was the real question.

You think your friend is worth more than this cocklodger. In time she will know you always knew that.
