Don't apologize for including her in the decision making process. In fact she apologized to you, so just drop it and move on. Don't even respond to her last text. It's just provocation.

Right now she's all about blaming you, and you apologizing for something that was not wrong will just enable that. The longer she keeps blaming you the longer till she realizes what she is doing to both your lives.

Btw how was reading no more mr nice guy?
