DO THIS!! my girlfriends birthday was yesterday. i called her and said happy birthday and acted like it wasnt that big of a deal, well i bought 12 roses 11 real 1 fake and i got her this cute card. i wrote alot of stuff, but at the end i wrote i will love you till the last one dies later that night i called her to come outside. also she had absolutely no idea, at first she was a bit angered but after she realized there was a fake rose. her face was priceless. do something like this to show her you care and that you put effort into things insteas of just buying a necklace or something. also a necklace would be a great addition to that gift. good luck and may you two last.
