You got some great advice from 2step right there ^^^ ... read and reread what he's saying to you.
You will serve yourself well if you try to RESPOND instead of REACT to situations. Reactions are emotionally driven, responses are logic and calm driven. Your feelings are all over the map, and that is completely understandable ... but they are YOUR feelings and you are the only one who can control them. Letting them drive your behaviour and reactions will not serve you well. Take a deep breath, and ground yourself.
As hard as it may be to hear ... she is not doing this TO you. She is doing it FOR herself.
