Musiclady-I know this hurts and I so sorry...
His lack of response, however, is like an affirmation that you need to go ahead and leave. It won't get better at this point, just worse. So leave while you have any semblance of sanity and self worth left. I know it's hard and it's hurts either way; if you stay or if you go. It's going to hurt. But you can get through it and slowly start to heal and become truly whole and be much much happier in the long run. Being with an active addict is like being half alive. His disease really sucks it out of you. Sure you can function...but you can't fully embrace life like you'd want to and know you're capable off. It's like a weight around your neck. And, you've already been so hurt. It's time to start healing. We're with you.
