I used to work next to this girl. I've known her for about a year and about four months ago we started becoming pretty close friends. We went out to lunch a few times, and I asked her out to a movie once and she said "yeah, we should go" but we never were able to set a time. She quit that week and we ended up not going.
This was about two months ago. I've talked to her about once or twice a week since then. I've asked her out a couple of times and she always said she was busy(she gave an excuse). I felt like I was starting to bug her so I decided to give her some room and after a week of not having contact with her she called just to say hi.
We're supposed to go with two other people as a group of friends to a show in a few weeks but I'm not sure how to act towards her. Do I flirt heavily and get touchy or just treat her as a close friend? Should I ask her out one more time? I really like her and don't want to ruin things by pushing too much. She's giving me mixed signals so I don't know what to do.
