Search Results: being let down by a girl

Bear with me, I've been out of the dating game for 10 years so I forgot everything.

I ended up having a class with a girl I haven't seen in about a year. We were classroom aquantinces , while i was talking to her she said we should hang out. We agreed to hang out after our class the next day (which is today). She didn't show up to class today, so during our class i texted her if "are you still down to hang or nah?" She replied "Not today. Another time for sure though."

I'm not sure where to take it from here. There could be number of reasons why she didn't show up to class or want to hang out today. I'm not sure if not being interested and trying to avoid the situation / awkwardness by not coming to class that day, or because of the other reasons.

Should I suggest another time, or tell her some days I'm free and see if she can make them, should i tell her if she ever wants to hang just let me know, or should i just leave it alone?

i was planning on suggesting a different day when i have free time and see if she can make it. If she doesn't show up or can't make those times without suggesting a day when she's free, i was going to tell her if she ever wants to hang just let me know. That way it puts the ball in her court, if she doesn't ask to hang out then she's not interested.

As I stand today, the woman I have (shamefully) fallen in love with (I am not the romantic type) is moving away. See my cover photo. She and I are in a peculiar area together, she is shy and giggly whenever I mention us together, she kind of ignores it but when I'm working (we work together) I always catch watching me and we basically spend most of the day, watching each other and smiling, I myself am not the kind of person to allow myself to be open and let someone into my heart and emotions but with this girl, I opened like a history book in Stephen bloody Fry's house, I love her, dearly and I think I may have missed my chance as she has resigned from work and is intent of moving to madrid for the foreseeable future, I have let things slide and pass me by, I stand back and let things happen but this time, I say... i'm in control, I won't just allow the idea of me never seeing her again come to fruition. And my pathetic veneration and solemn determination has made me wonder... should I pursue her, travel to Spain and make a grand gesture that I haven't thought of yet. So rather then being a big dick fuckboy and just grab ass and seeing what happens, I am going the hard way, should I travel to Spain or should I let it go (as that blonde bitch from Frozen would say). Now, before you answer, a little other fact is, as I post this, I am on a two day window of her still in the uk so I am continuously plotting but the big question still stands, stay or go? Also if I do go, there's still a chance of failure. Slight chance.

If your reading this far down, kudos for putting up with the asinine ramblings of a mad man but this is the first time I don't know what to do and needs... help?
Thanks spectators
Gimme what you got

Stay and let it go (Nay) or Go and win her (Yay)
