I agree with Giga, dont do the whole grandure thing of facebook. You need to do something personal. You have to show her youre doing what needs to be done. But also you need to be doing it for yourself first and foremost. When she sees the true effort is for bettering yourself, you will see she will find a whole new respect for you.
Gawd dont do the Facebook, its too childish at ya'lls age. Its a nice romantic gesture, but not what she needs.
goodluck!
everything happens for a reason...beginning to wonder why.
