Well, you can speak in tongues, be obtuse and drip feed, of course. As longaas you accept that it's going to piss people off and lead people to the conclusion that it might well be you in the wrong here...
Is your husband normally supportive? If so, you might need to consider that you're in the wrong. And no, I don't think someone should always support their spouse. I wouldn't if I thought they were in the wrong.
Why is someone who would put your windows through your friend?
In fact, why is someone who would put your windows through left caring for your children? Is she an ofsted registered childminder with whom you have a contract or a casual babysitter you are calling a CM to make her transgression of not turning up to work for 3 days appear worse? Actually, scrap that, I know the answer because a CM looks after children in their own home. So, if she's doing you a favour, albeit one she receives money for, then she is entitled to withdraw that favour if you've pissed her off.
Do you think you're better than her?
I suspect you're not telling the full story about the exchange, tbh. Unless you are all reactive and emotionally illiterate, of course...
Tbh, this woman does sound a little unstable, but then she's your friend and CM (presumably by your choice) I suspect you're both probably as bad as each other and your husband is stuck in the middle of it!
