You really have done NOTHING wrong - you are not responsible for how she reacted. Maybe she felt betrayed that you havent told her before (not your fault she feels that way). Her reaction was staggering and I cannot imagine why she responded so emphatically negatively to an honest admission from a friend who loves her.. I truly hope that firstly, this doesn't discourage you from being yourself and opening up with others, and secondly, that she gets in touch to reconcile her behaviour with you. You are a lovely woman - you have helped me so much on here. I truly hope that after she has time to process what you told her she will realise that there was nothing malevolent about your admission and will get in touch to reaffirm that you have done literally NOTHING wrong. Big hug sweetie xx
