I'm truly sorry she did that to you. Unfortunately we get the luck of the draw when it comes to our parents. Some people are lucky. Some of us not. Please, listen to your family & friends and don't waste your time on her anymore. It's obvious from her actions and words that she's a selfish woman who will always disappoint you. You're lucky you have other women in your life who provided the mothering you needed. Use them as role models & spend time with them. Sadly, it's time to close the chapter with her & move on. Guaranteed, she will contact you down the road only when she needs something. When that happens, remember how she treated you, was never there for you, and, that you owe her nothing.
