Cocaine is a horrible drug. My partner of 8 and a half years had been taking cocaine!! He was depressed and on anti-depressants. He has lied, cheated, disappeared for days on end. I have always been supportive. But now i know the truth about the effects of cocaine. It makes them selfish, withdrawn, and eventually they loose themselves. You may try and save them, make everything better for them for a while. They can only help themselves be better. I have lost myself along the way. You become so consumed with making it better for them that you stop concentrating on you. Write down the pro’s and con’s of the relationship. Think about what he does for you and what you do for him. Is it balanced? Only you can decide what your future looks like. I wish you all the best.
