It's a question about freezing out, here's some background information if you want it, if not skip right ahead to the bold
Alright I was kinda chasing this girl. I know I know, normally I dont chase either

Anyways, LJBF me after hanging out with me. She just came out of a relationship (I seem to attract those ones lately) yada yada yada.
Since she lives in a dorm and I still live with my parents I stole (think it was adam lyons?) this idea to escalate at her hoom. Set up a movie night with the 2 of us and miss your last bus/train home, so you'd have to stay the night

So far the plan, here's the execution:
I set her up during for this during a conversation on Messenger:
She initiates a college related conversation, we talk for a while.
Me: Anyways I was watching this movie with my sister, don't want to keep her waiting

Her: Oh, real quick then, what movie?
Me: Some twilight crap (Can't remember if it really was or if it was something else)
Her: Oh I liked that one!
Me: Meh, not really my type of movie, my fav movie is Peaceful warrior (highly recommended btw)
Her: Hmmm never seen it.
Me: You have never seen Peaceful Warrior? That's crazy!?! We are going to have a movie night together, I'll get the popcorn and the movie, you arrange the cinema

You have a microwave right?
Her: I don't
Me: Then I'll get Ben and Jerry's, you just make sure you have a couple of clean spoons

Her: Ben and Jerry's!! And yeah I've got like 20 spoons

Me: We'll pick a date later, I'll watch the rest of the movie with my sister now.
Like a few days or so later, texting her
Me: Hey curly
(nickname doesn't really translate well but it's a joke when you call a women with straight hair curly) I dont have to train on Fridays (vacation or something), so we can arrange our movie night then. What kinda Ben and Jerry's did you love again?
Her: Hahahaha Do I have any say in that?

I'm going to have to disappoint you, cause that's not gonna fly. I have to work and learn for exams. So sorry, another time mister! (Maybe you might find someone else for your movie night

)
Alright she's been like this one time before, agreeing to a date then backing off....So I decided a freeze out. Completely ignore her on facebook, if she texts me don't text back and just be short if she holla's me during college.
Question is.....how do I come back from a freeze out? Do I need to give her an excuse for ignoring her for 1 or 2 weeks? Not mention it? Invent a personal drama? I have no idea how to go about it. Any idea's, suggestions or help would be appreciated
