FYI :: I am a longtime listener but this is my first time using reddit so sorry for any formatting issues.

So like the title says my eldest child (12F) believes her father “groomed” me. At first when she approached me with this I kinda laughed because at the time I wasn’t that familiar with the term and from what I knew about it I thought maybe she was the one confused on it. But now, she has become very distant from her father and acts weird in front of him. She was always a daddy’s girl so this is breaking his heart.

Anyways, a few days ago she approached me for the third time about this “grooming” thing and finally I sat her down and asked her what she thought grooming was. I listened to her explanation of it and then looked up the textbook definition to compare and she was almost spot on. At first I believed maybe she learned this from the kids in her school because they often pick on her for being biracial and maybe they got tired of that and decided to find something new to pick on her about. But this was shortly proven to be a false theory after she told me she learned about it from the devil app itself, Tik Tok. She said “She did the math” and it seemed like from our ages when we met (2007) that he “groomed me”. I was quite taken aback and had to explain to her that when we met her dad was 35 and I was 20, both legal adults. Her father is my first love and my first husband. I am his second wife and the only woman he has kids with. Though, even after I explained she still is acting weird towards her father. My other two children (9M & 4M) have also started noticing her weird behavior and I’m worried that soon they will start asking why she is acting like that.

So what do you all recommend I do?

TL : DR - My daughter found out the meaning of grooming on the internet and now believes my husband (50M, 35 when we met) “groomed” me (36F, 20 when we met). This is causing a problem in our family and I don’t know what to do.

Edit :: For extra info my husband’s ex wife is the same age as him just two months younger. They ended their marriage due to infidelity on her end which led to her getting pregnant.
