She called me in tears yesterday because she was packing up and it got too hard for her to deal with, and asked me to come over with food and to help her out. In spite of the advice I've been given, I decided to go over, helped her finish packing, and then we watched a bunch of videos on youtube. I don't think getting that involved automatically friend-zones me, as she is leaving tomorrow and just won't be around after that. Then tonight we got together with another coworker for drinks and to say goodbye, and when we left we hugged and I told her to keep in touch. Her response told me she had every intention to already, and in general I feel like a genuine connection is there.
I guess the kind of advice I'm looking for now is along the lines of developing a long distance relationship, as that is something I've never done before. I intend to keep our communication light for now, check in when she arrives and maybe once a week ask how things are going. I'm not sure what to look for to know when she's past the breakup and possibly ready to move on, and I have a feeling with her I'm going to have to deal with hints at that time and I am just not good at picking up on those.
Thanks for everything so far, I don't think she'd feel the same way now if I did what I thought about doing from the start. In fact, I'd probably be the creepy guy that crossed some boundaries and made a bad time worse for her, so again, thanks.
