I can't help but focus on the issue of your husband's girlfriend not growing up as a self sufficient adult; secure in her ability to take care of herself as an empowered woman. No doubt she doesn't want to give you space..because that means she would loose her comfy place and financial security....How much of your husband is her "Boyfriend" and how much of him is her "sugar daddy"?
