Your poor grammar and over use of pronouns makes that very difficult to decipher; let me try.
You are shacking up with a man who is not even divorced. Your boyfriend's daughter is living with you and your honey(who is another woman's husband) . Your boyfriend's wife does not want HER daughter living with you when her HUSBAND (with whom you are shacking up ) is not at your house.
Does that about sum it up? How can a woman with ANY self respect and sense of decency allow this to happen?
The mother of that child can certainly report her as a runaway, and you should not even entertain the idea of having her in your home against the wishes of the child's MOTHER.
Good Grief.
And your house is not that girl's home. It is simply where her dad is doing some women who means nothing to the daughter.
Please tell me you have had your tubes tied.
