That is normal from now on. It's the sign the woman wants nothing to do to you and you have no chance of rectifying anything. She is telling you to go away and doesn't want to do anything that will get your hopes up. Effectively she has poisoned her mind against you and even things she remembered fondly of you, she now twists herself into somehow hating.The thought of her being cold and cruel to me is part of what has been stopping me so far from contacting her. She was already cold during the breakup. I kinda wonder if she is still like that or if she went back to normal now. I also wonder if she even thinks about me anymore or is she has just moved on already.
Go put this amount of energy and effort into finding new women. You are done with her.
