If you choose then it's fine. If she chooses then she's a slut. If she agrees to your choice she gets to be with you. If she refuses to agree to your choice then you will never speak to her again. Are you a Lannister by any chance, or are you just stark raving mad?
Why are you being intentionally obtuse? If she has a boyfriend its not okay for her to ACTIVELY seek other men. She should break up with him if she feels that way. If she however is passively courted and then chooses to leave him for another man thats her choice. Shes not married and has no obligation.
And I never said I would never speak to her again, just that our relationship would regress back to friendLY not friends.
How many more people need to tell you that you're wrong and creepy before you accept it? ---
Been a murder, over in Riften. Some old lady who runs an orphanage. Those poor children must be heartbroken.
