Once i pulled out a nice photo of both of us from the album, and bought a nice frame and gave it to her with some flowers.
My gf is easy to buy for tho cos she LOVES chocolate. cliché, yes but she certainly adores Dove caramel hehe.
anyway, i never have money so i recently made her massage vouchers on an a4 bit of paper and printed em up nicely. 4x 5 min massages, 3 tens and a 20min. shes LOVING them (and btw, encourage happy endings on the terms and conditions bit on the back) It worked for me!
sorry for the R rated stuff, but what im trying to say is, its the thought that counts. go pik some flowers and put em into a nice litttle bunch with a ribbon, or make her a card, take her out to dinner or even better, cook yourselves a meal. Go for a romantic drive or just spend the night in watching a dvd with lollies and stuff.
