Daughter wants to move in with her mom

cant help you much because I don't have any kids and single but looking at it from a teenage girl's point of view because it wasn't that long ago I was in those shoes:

Maybe try explaining to your daughter your concerns and give a reason why you think its not a good idea. I have adoptive parents who were strict but when they told me I couldn't go somewhere or do something....they gave a reason why.

As a kid its natural to rebel to a direct command that seems dumb at the time because you don't understand why. It feels like your parent(s) are just trying to oppress and control you and keep you from any fun times that your friends brag about which later when your older you realize were just BS anyway ....but as a teen its hard to see that.

If you can convey a very good reason behind your concerns you might get her to agree with you. When my adoptive parents told me not to go certain places or do certain things they took the time to give a detailed explanation behind their reasons and it made sense to me and I had no choice but to agree seeing the logic. There were times I wanted to rebel and do something anyway but I pretty much always backed out of rebel mode because it didn't make sense to push it knowing the dangers and consequences.

Communication might make her feel like you see her as a smart person and that might make her respond favorably because she will feel responsible to make better choices.
