I personally would have answered her when she texted.
Answer, don't answer it doesn't change anything.
Having said that you are perfectly in the right to communicate to her that she fired you as her BF and that she should not contact you for things that do not involve finances or the kids.
The problem is it can come off as being petty and pouty and you are trying to punish her. If that is how she viewed your behavior in the past it is just more of the same.
