find out what her favourite food is...then make it for her on her birthday.....or if its to complicated buy or order it, set the dinner table with candle light, find out what her favourite flowers are and have a bunch on the table, and a flower on each step leading to the bedroom and a couple on the bed and candle light all in the bedroom or bathroom, have a bottle of wine chilled, for dessert you could get like a heart shaped little cake, or get like ice cube makers which are shaped in hearts and melt choclate in them and leave them to set and have them on the table, all the little things count more, coming from a girls point of vierw that would be the perfect evening for me, id alos love it if my partner hand made my card, evan if it wasnt perfect a big mess lol id really appreciate it, hope this helps
