I know there is such a thing as a motherly bond. Some Mothers would do anything for their child even if it's illegal. However, this woman is doing everything for her child even if it means to hurt her adoptive child. That's not a mother. You don't have a conscious. And you are not aother to your adoptive child. Equal treatment is the bare minimum
At some point if I were FL I would been like "Who wants to be at Golden embroidery anyways? Y'all have low standards. Look who you excepted here (and point to the sister)"
This might be a make or break situation....If FL's adoptive mother meets with her bio parents because she told them she adopted their daughter and they will assume it's the sister or she will make them believe it's the sister (could easily get FL's DNA and fake a test) even though they saw her as a child and growing up....this will be beyond stupid. And although your "heart" (at least the father's) seems to be in the right place concerning their daughter, if they go along with that kind of lie, they don't deserve to find her
Can we all agree that FL's bio mother doesn't want to find her? Because if she is found her lies would be exposed and everyone would know that it's her fault that FL disappeared and that her brother in law died
