I'm unclear about what you mean Complex. I mean, I get that you don't want to be her "friend", ( but now, or down the road ??)
but you seem to think that being pleasant NOW on a daily basis is perhaps bad.
Meaning what? Being a jerk or arguing with her (again) won't make her care more about losing you.
What are you asking, specifically? What do you see as your options?
