To add to what JM said, also make sure you don't bully her and be a jerk about things you both want. If it is a non-negotiable for you, then be cool, calm, collected, and consistent with why you want it, think it should be this way, etc. Don't let your emotions drive your actions. Be reflective -- show her that you're willing and able to be thoughtful with respect to the situation, and that you're not going to make rash decisions, show her your "more of the same" behaviors, etc. Like cherrisher said -- let her go, and witness changes take place as a result. Maybe they'll be changes in her feelings, but they will definitely be changes in YOU and YOUR R with her, and they will be for the better.
