welcome to the forum. There is nothing wrong with you having problem detaching. You are so so very new to this. Do not be hard on yourself.
No need for any kind of feedback from your side. You need to fix you first. Do not worry about her. You need to let her go. She has to find her own way, and you butting in will only make her resent you. I must reiterate, you CANNOT do anything to help her. Any interference will be viewed as meddling and controlling. BUTT OUT!
Stop worrying about her, you have your work cut out. And no, You do not need to move on, but it is imperative you move your a$$ forward. Do not get stuck. You have an enormous amount of healing to do. And growing. A lot of things will start to fall into place when you start moving forward.
You need to start enjoying being by yourself, as long as you pine for your EX, she has you on her hook. And as long as she know she has you on the hook, she will not turn back to you, as you are only her plan B. She HAS TO FEEL THE LOSS OF YOU! She has to see that you are not there for her. It sound counterintuitive, but you have to trust me on this.
