I think you need to ignore her texts. The way she is treating you and disrespectful. You need to minimize your contact with her.
If she finally comes around and asks what is wrong then you can have the conversation that you do not appreciate the things she is saying to you or how she is treating you.
Dont expect this to go well. say your peace and let her go a little crazy then walk away. She will need to time to process.
see what happens after that. I think she knows she still has you if she wants you and will treat you however you want. Time to stand up and make yourself known.
