Her mother is kind of shitty, engaging her daughter with guy eight years older. I am not that knowledgeable, but isn't it what some may call grooming? It's definitely not the healthiest relathionships when you introduce your ten-year-old daughter to an eighteen-year-old guy and say that she has to marry him in the future. I am generally against arranged marriages, but this one seems especially bad. The guy has a mostly formed independent pesonality, while the girl is still a child, whose personality and worldview are easily affected by other people.
