My boyfriend has three grown children. I get along with the oldest two but the youngest is not very likable. She is18 disrespectful and a brat. She only has contact with her father when she wants something.
It literally makes me sick when she comes over to the house. She always ends up ruining the day.
This leads to fighting with my bf. I literally just don't like her as a person, she constantly talking bad about myself or my children on her Twitter.
