You really need to understand that as a man you need to not be scared of losing THIS. You need to know, that you will be okay with YOUR decision.
This $h!t is abusive man, and until you realize you are okay without this, there isn't much advice in the world to give you. I wish you luck, but don't let the fear of her saying "it's over" ever dictate your happiness.
Until you stand for what you want, she will never respect you.
