Besides the Big Brother aspect of this that is offensive, she has told you that your
birth control must be the Pill when you could just as easily use an IUD,
and is trying to bring your boyfriend into it even if you might change boyfriends sometime. So not only is the approach heavy-handed, it is absurd. What she DOES have the right to do, is ask you (not your boyfriend) to sign an informed-consent document about Lexapro. Any doctor would have the right to do that.
