On the spur of the moment, I spent $5400 on return airfares and other expenses to join my girlfriend in Iceland for the remaining 3 weeks of her 5 week trip over there, although I did borrow $2000 of it from her.

But for someone who I will end up marrying and spending the rest of my life with... it was just a minor expense, because I got to spend 3 of the best weeks of my life in one of the greatest places on earth with her and it was well worth it.
I'm not one to be getting all romantic-tradgedy and placing my heart at the alter of death for a loved one, so I'll leave that decision until the day it has to be made, if it has to be made at all.
