She has idolized her own appearance and thinks you owe her lust. She is not really a high maintenance woman. She is just an insecure and abusive woman who has put her sense of importance at the forefront of everything in your life; now that you thought you would show her that all men are not dogs. But, what happened to the last one? She will break up with anyone including any modern day simile of Paul the apostle(1st Corinthians 13) when she thinks her own sense of self importance has not taken priority in the relationship. All you said is that there is a subway delay or that you were delayed by an office meeting. She asked you to prove it and now you are taking photos of board meetings and of subway delay notices on the electronic notice board. Just invest the time necessary to take a few photos. She already envisioned emptying any joint account you wish to open and she always has a roster of 4-5 others to prove that she does not need you anytime there is a subway delay. She will break up and call the next one. A woman who says
"all men are dogs" has already told you what she is to all men.
