Sex and Drugs..

My bf is a recovering heroin addict. He was two years sober until one day his family came to my house attacked me of influencing his drug use. I was confused. So I bought a drug test, been living with him and didn't suspect shit. He confessed to using. I felt like fool. Our bond was great, our relationship perfect, sex amazing. The day I found out that all went to hell. He is now 2 months sober and 2 months my hearts been broken, 2 months no more sex.. I'm so sad. We were so in love. And I'm trying to get over it all.. But he doesn't even want to have sex anymore. Like the day I found out, he begged me back and the same time lost interest. Advice please someone.
