So I'm in my relationship and it is about to be 6 months

Destiny

I have no clue what i am going to do for him. I'm currently a Junior and he is a Sophomore. I have wrote him a lot of letters, drew him pictures, gave him stuffed animals, created origami and I created a periodic table puzzle( he finds the letters on the periodic table and sees what i wrote)but i really want it to be even more meaningful to him. I love him so much and i know most people say that highschool relationships will not last but we have never had an argument, we constantly talk to each on facetime and we hang out out of school all the time. Does anyone have any ideas i really need help.
