What Should I Do About My Boyfriend’s Drug Problem?

I’m 19 and my boyfriend is 20. We have been together on and off for 3 1/2 years. He used to have major drug problems (heroin, pills, x, shrooms, alcohol, etc.) and that was usually the cause of our break-ups. He went to rehab, relapsed, and sobered up the second time alone.We lived in Ohio, and a year ago, he moved to Florida to live with his mom. He got a job, a car, and began to change so much. We worked things out, and I moved down to Florida a month ago.

For 3 weeks, everything was perfect. I couldn’t have been happier. Then, I started finding pills & needles. The pills are xanax (bars) and blues/roxys.. whatever. Of course, he always had excuses for why they were around. But I know when he’s lying and when he’s not sober.

Anyway, the past week has been hell. I don’t know what to do. He refuses to get any help, because he says he isn’t on anything. He gets mad when his mom and I try to talk about it. What do I do?!

Please, do not say, “leave him.” I am a smart girl, and I know I sound dumb to not leave. But I love him so much and I want what’s best for him. Also, I’m scared that if I leave, he’ll abuse drugs even worse, or kill himself.. honestly.

I’ve written him notes about how I can’t do this again, I’ve cried and begged him to stop. I don’t know what else to do. If you have ANY suggestions OTHER than leaving, pleaseeee help….
Thank you everyone.. I may be leaving in a week to go back to Ohio..
