what should i do

I am i love with my high school sweetheart. we were boy friend and girl friend in the younger grades and then when i had to move over a 1000 miles away i didn't see him anymore at all and my heart missed him dearly it was very difficult to go into a new relationship and he was the same way. anyways three years later i move back to where i used to live and i see him again oh wow if was lovely we couldnt stop hugging each other. But later on that day i found out hes changed a lot over the years. he is in to drugs pretty badly now. before it was just a little pot there and a little pot here but now he does LSD, DA, shrooms and so on. i do think i can stop loveing him and love someone else hes my everything the only person that i love but i CANT stand the favt that he does drugs oh what should i do???

If he does not stop using drugs, and if you continue with him, he will destroy your life.
