JUST call her because she might not be angry with you, she might actually be embarrassed to say your brother-in-law was useless!

And if she is angry, all you can say is “I’m sorry, I feel terrible for you and genuinely thought he’d do a good job”.

I think it needs one of you to make that first move. Just speak to each other.

It’s not your fault the job went wrong – that’s down to your brother-in-law. You recommended him in good faith, and sometimes in life these things happen.

I’m sure your friend doesn’t blame you, but might be keeping her distance because she doesn’t know how to deal with it. But if you’re good friends, you should be able to talk about it and move on.
