Search Results: how far do i pursue her

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)
