Forget him, the only stud you need in your life is me! =P
How serious are you guys? Maybe you can turn the table and propose to him, I know it's a cliche on Valentine but for you to do it, I guarantee he will never forget Valentines day again.
Most men love peace and quiet, buy a movie, get a bottle of wine, and enjoy the night, if you really need to buy him something buy a watch to go along with this.
If you really want to mess with him tell him your pregnant.
