Our psychology is one that reacts, no matter how exaggerated the claim is, according to how we believe we have been treated by others. It is highly probable that she is intimidated by you, and feels that you inadvertently stand between her and her desires. She may or may not be aware that she is doing this to vindicate a perceived transgression against her ego. As a Christian we are asked that in respect to the example of Christ, by whom we are saved by grace (receiving that which we are not worthy of), to react according to how God has treated us (thus to follow Christ in ministering the gospel of Grace in word and in deed after His example), rather than avenging and vindicating ourselves. For the problem with revenge and recompense is you can only exercise this right if you are perfect by the law (for Christ warns, "as you have judged so shall you be judged"), but we are saved by Grace and should bear fruit according to what God has bestowed upon us rather than trying to avenge ourselves, which "resists not evil."
"If ye then be risen with Christ, seek those things which are above, where Christ sitteth on the right hand of God. Set your affection on things above, not on things on the earth. For ye are dead, and your life is hid with Christ in God. When Christ, who is our life, shall appear, then shall ye also appear with him in glory....(Keep reading yourself; Col Chap 3).
For the contrast is surely not of Christ. "He that saith he is in the light, and hateth his brother, is in darkness even until now. He that loveth his brother abideth in the light, and there is none occasion of stumbling in him. But he that hateth his brother is in darkness, and walketh in darkness, and knoweth not whither he goeth, because that darkness hath blinded his eyes...For this is the message that ye heard from the beginning, that we should love one another. Not as Cain, who was of that wicked one, and slew his brother. And wherefore slew he him? Because his own works were evil, and his brother's righteous. Marvel not, my brethren, if the world hate you. We know that we have passed from death unto life, because we love the brethren. He that loveth not his brother abideth in death. Whosoever hateth his brother is a murderer: and ye know that no murderer hath eternal life abiding in him. Hereby perceive we the love of God, because he laid down his life for us: and we ought to lay down our lives for the brethren. But whoso hath this world's good, and seeth his brother have need, and shutteth up his bowels of compassion from him, how dwelleth the love of God in him? ...If a man say, I love God, and hateth his brother, he is a liar: for he that loveth not his brother whom he hath seen, how can he love God whom he hath not seen? And this commandment have we from him, That he who loveth God love his brother also." (Various verses of 1 John)
