I don't mean to sound too negative..really, I don't..BUT if your
husband isn't ready to work as a unit with you, it's a lost cause. I
would not allow a teen to move into my home without agreement in
advance on basic rules. All three of you need to sign a written
agreement and the consequences for not following through.
To me the first and foremost rule is medication compiance. If she refuses to take the medications don't let her move into your home. Let
her Mom do whatevr seems best to her in her hometown. Passing
problems on to another is not right for anyone in the extended
family..period.
I hope you all can get on the same page and that you can stick to
your guns. Good luck. DDD
