Time and distance will help Wolfman. Keep reaching out when you can. Validate her feelings when she expresses them - especially when you don’t agree. This is not a win-lose situation. It’s a win-win or lose-lose and you have more power in this than you think you do. I don’t think I would waste time going down the parental alienation route. Even if the world agrees with you, how would that change the situation with your daughter? Would she suddenly feel differently? I highly doubt that she would. You need to accept where she is at and go from there. Show her that you are not the person she thinks. Keep your temper in check, resist the need to defend yourself or argue with her, do NOT talk about her mom and mom’s bf, etc… Focus on your other kids and when you see your daughter, even if it is just in passing, make sure you are warm and friendly towards her. Eventually she will get curious and start to question her beliefs about you. This will not last forever. Feelings change and hers will too. Just be as patient as you can possibly be and let her lead the way. If her mom is as manipulative as you say she is, your D will eventually see that and start to question things. This will be on her timeline, though, not yours. Best of luck. (((HUGS)))
