You're addicted to your addict. I know cos I am too. Just like he craves his drug, I crave contact with him (good or bad contact, it doesn't matter). We once normal, intelligent people think of doing some crazy stuff just to get one moment of feeling that he's thinking about me but, as has been said, they're too numb to think of anything other than continuing to get high. There's a greater chance of him thinking about you if you ignore him but, then when you give in to his attention, poof! They're gone again. That's the insanity of it. Cos we're raised that if you live someone, you show it but with addicts, if you show you love them, they use it against you. Stay strong.
