<human>: Can you condense the text into a few key points?

I met a "Jackie" at work, we talked, shared a few laughs, and she asked for my facebook and number. 

I invite her out to the movies with me, and she agrees. We decide on a movie, and set a time. Day of, I check with her to confirm its still good, and she turns me down, saying she has too much work. 
I thought that I just got rejected. But then she invites me to come over to her apartment, so we can do work and still hang. I head over, and after about half an hour, her housemate comes in and they talk about the past weekend for the rest of the time that I'm there. A bit later, we part ways when she needs to go grocery shopping.

After that, finals were looming, and I didn't manage to get together with her again. I haven't been sure how to proceed with anything ever since, and the most I've done is tell her that I think she's cute.

How should I ask her out, or is it too late for me. I want to get to know her some more, potentially pursue a relationship, but for the most part, I want some advice doing anything besides the -nothing- that I'm currently doing.
<bot>: Girl cancels a movie date, but she invites me to her apartment and her roommate gets in the way, and haven't seen her since final exams-- how should I ask her out?
