Is it wrong to want my fiance's daughter to live somewhere else?
Well, why do you want her gone? Has she done something?
She is an awful child. She makes my life miserable.
You should know that partners with kids have baggage. You should try to talk to your partner and make a joint plan for the problems.
She takes care of the kid 24/7 and doesn't let me do shit.
Well, you two need to talk to each other about this arrangement. You can't just expect her to cut off her own daughter. You will all be happier if you can make an arrangement that works.
