I'm sure I'll get bashed for my comment...but I think I would have apologized in person. You could have then looked her in the eye and apologized and followed up with: "let's work together on any changes to the rules for out little girl so that we don't confuse or upset her again".
Texting, to me, in a case like this is very impersonal....but that's my opinion.
Please note, there is no right or wrong way to do things, but sometimes, we have to try different things. Hopefully, your text will smooth the waters at home.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
