Dont worry, she will never forget what he did to her and she wont weaver, she will completely destroy him and make him pay the price. She may look like shes softening but more towards the prince than her father. She decided not to blame him for what he did as her husband since the current him is not her husband who "betrayed her" but just a child. While her father is still the same person who would treat her like a goddamn doll and sell her to men if she didnt have any powers. Shes aware he is still the same, he never changed and will never change, the only thing that is different is her value in his eyes, before she was worth just some money, now shes worth power and prestige. Shes behaving so that he will 100% support her and help her gain power, but as soon as she is strong enough she will stab him in the back.
I'm glad FL is smart enough to recognize that her father is only being nice to her because of her powers. I thought for a second there that they were going to give him a redemption arc, which he does not deserve. FL says that she will use him for all his worth.
