I read a lot of "I feel like" and "I think" in your above posts. You need to move away from assumptions and reacting to her actions.
Take some time to think about what you want in your relationship, and how you want to go about doing that.
As for being too aggressive, you can set boundaries without being aggressive or overly confrontational. And I can guarantee that anything you do to change things or assert yourself will be met with hostility -- you will be moving out of her mental image of what you are like, which means she has to figure out how to deal with you.
