I’m so sorry about the situation with your daughter. You may have to accept that for a while, you may need to sit back. Continue to make appropriate attempts to reach out, buy her nice Xmas presents, tell her you love her, but work on accepting the situation too. You can’t force her - this will be more like coaxing a squirrel to eat from your hand. Patience, patience. Kindness. She’s hurting, she feels betrayed and replaced. She might also feel like mom “needs” her to take her side.
Kids change. Without focusing on resisting you, she might eventually turn more of her teenage rebellion on mom. Heck, she might come to you a couple of years from now and ask to live with you. Just be steady, loving and supportive but don’t push.
