Do you think this could last?

let me make this as short as i can possibly make it. we are in our teens we and we started dating last august we dated until october broke up until december and have been dating ever since. that was our only break up. im incredibly happy with him and words cant describe how i feel about him. he one of the best boyfriends out there he treats me really good he constantly tells me he loves me and makes every effort to see me whenever possoble my family likes him and his family likes me. he hasnt cheated on me and i havent cheated on him. we go to different schools which sucks. i trust him with everything inside me hes earned that trust in lots of ways and he trusts me...i dont think i could ever be okay if i lost him i wouldnt ever be able to move on..people have told us they could see us bein highschool sweethearts...we have a really good relationship we can be totally honest with each other with anything...no other guy in the world can compare to him
