I have heard many similar comments from my W initially.
You will need to begin the process of giving up what you cannot control. You can't control her, what she does or what she says. You CAN control You - how you react to her.
Put the focus on you. Make changes in yourself you need. But make them for YOU, not with the intention or hope of winning her back.
Work on your self-confidence. That is an attractive quality. Maybe it attracts her back, maybe not. But you are better off in the end for you, and your daughter.
