My partner of 2 years, is a heroin addict, he has been for 17 years, when I met him he was only on meth, he has been secretive going off place not saying where and when I ask he says is dropped things at work but I know different, he has admitted he is back on it and just lately hes moody, lies, sleeps, lazy, his appearance is vile, will not help around the house, hes happy when he has it but miserable when he does not I’m at my wits end, I can not do this anymore, I have tried to support him and again he just throws it back in my face. I feel very alone right now, I love him and have tried all I can to help him get help but I just feel he does not love me and this drug has over took our relationship, is this the end of us?
