You’re not the A here.
Your reasoning is sound and fair. Your stepdaughter’s request isn’t a real 50/50 split; it’s only possible if your biological daughter isn’t there. That won’t work, and it would be very unfair to ask your daughter to move out every other week just to make that work. Your stepdaughter may have mixed feelings about the divorce or even be having problems with your daughter. That’s something her mom needs to help her with, not something that should hurt your child’s home stability.
You don’t want her, so you’re not refusing to take care of her. You’re refusing a situation that would hurt your daughter and make your home a mess. The decision: NTA. You’re keeping your daughter safe, and it’s up to you and your ex to come up with a custody plan that doesn’t make the kids fight.
AITA for refusing to have custody of my stepdaughter?
