don't splurge, man! see, if this is how it's gonna be at six months, she's gonna expect something bigger and better by a year... then two years, then three... and by the time you are married to her, you're spending a year's worth of salary on something for her. don't do it!!!! it's been three years with my girlfriend and i finally broke the 900 dollar barrier. at your rate, you'll break the 900 dollar barrier in a year!
but if you are gonna get some sweet love action.... just kidding. i had a neighbor and her bf go to cirque do soleil in vegas... heard it was one of the most amazing shows ever. it just might be worth it to go with her for the hell of it and not make it a gift, know what i mean?
actually, now that i think about it, if you divide that by two, you're only spending a little over 200 on her. not bad. go for it man!!!
