This girl knows i like her but how do i ...?

HOW DO I TALK TO HER.? I TOLD HER I LIKE HER LIKE ON December AND THEN A WEEK LATER I GOT HER A REALLY EXPENSIVE GIFT. I GOT HER A SOCCER JERSEY (PUMAS) THAT’S HER FAVORITE TEAM, TICKLE ME ELMO, CD FROM MY ITUNES OF HOW I FELT FOR HER, AND A HALLMARK CARD SAYING SOMETHING SHORT AND SWEET. SO I GAVE IT TO HER THE LAST DAY OF SCHOOL IN December. I SAW HER IN THE MORNING AND I STARTED TALKING TO HER THEN I TOLD HER I GOT HER SOMETHING I NEED IT TO GIVE HER AND IF SHE COULD WAIT FOR ME BY HER LOCKER AT THE END OF THE DAY. SO SHE WAITED AND I TOLD HER IF SHE COULD GO TO PARKING LOT BECAUSE I LEFT THE GIFT IN MY CAR. SO WHEN WE GOT TO MY CAR I TOLD HER THIS IS THE GIFT I GOT YOU I KNOW IS KIND OF BIG. SHE TOLD ME YOU DIDN’T HAD TO GET ME ANYTHING AND I SAID YEAH I KNOW I DIDN’T BUT I WANTED TO GET YOU A CHRISTMAS GIFT. SHE SAID THANK YOU AND HUG ME AND I SAID SO I HOPE YOU LIKE IT AND MERRY CHIRSTMAS AND SHE HUG ME AGAIN. SO WHEN WE CAME BACK FROM CRISTMAS BREAK WE DON’T TALK AS MUCH WE DON’T HAVE NO CLES TOGETHER BUT WE HAVE A LOT OF EYE CONTACT AND WE SAY HI IN THE HALLWAY DURING PING PERIODS AND WE USE TO DO THIS TOO BEFORE I TOLD HER I LIKE HER. THE GIRL TOLD ONE OF MY FRIENDS ALL THE THINGS I GOT HER AND THAT SHE WASN’T EXPECTING IT, BUT SHE LIKE IT, AND IT WAS REALLY SWEET. I REALLY WANT TO TALK TO HER BUT I REALLY GET REALLY SHY. SOMETIMES SHE WALKS BY HER SELF AND I KNOW I HAVE A CHANCE TO TALK TO HER BUT I JUST BE SAYING IN MY MIND SHOULD I OR NO. THEN BY THAT TIME SHE GOES INTO HER CL. BUT I DON’T KNOW WHAT TO SAY? AND I WANT TO ASK HER OUT FOR PROM AND I THINK I SHOULD TALK TO HER MORE SO WE COULD GET TO KNOW EACH OTHER MORE. I WAS GOINGTO SEND HER A LIKE A DOZEN SAYING: SO I REALLY LIKE YOU AND WILL … THEN SEND HER SINGLE ROSES TO EACH CL SAYING 1.YOU 2. GO 3.TO 4. PROM 5.WITH 6.ME. THEN THE LAST ONE PUT IT IN HER LOCKER TELLING HER TO MEET ME IN THIS CL ROOM WERE IM A BE AT. THEN ASK HER IF SHE WILL GO. both seniors. WHAT DO I SAY TO HER DO I BRING UP THE GIFT OR WHAT DO I TALK TO HER THE ONLY TIME WE SEE EACH OTHER ARE DURING PING PERIODS AND THEY ARE ONLY 5 MINUTES. SHOULD I ASK HER OUT???
