It might help if you consider that the feelings of profound longing you feel now for him, and the deep desire to be with him, and the intense obsession you feel now regarding him.....is also his experience:
But it is his experience with heroin.
He is as unavailable to you today as if he were living on the other side of the globe. He is disconnected, disengaged, and disinterested. He is in active heroin addiction. And his goal today is to use more of it.
Stay in the present. Do not make up stories in your mind which have not happened, whether good or bad.
When the shock has subsided and you are able to move your body again and think in an organized way, prepare a plan of action based on the reality that your husband has abandoned you and do whatever you must to build for yourself a secure base, a safe home, a support network, and some form of counseling or 12-Step work.
You are paralyzed right now but that will pass. He has escaped the realities of life and responsibilities, but that is not your path. When you can, gather your courage and your intelligence and make a change. Waiting for him is all right, if you want to do that, but waiting for him with an expectation that he will at any time in 2013 be able to meet you as an equal and healthy partner is, in my view, unrealistic.
He cannot meet your needs and that will be the way things are for quite a long while. So it will be up to you to take responsibility to meet those needs. We have all here had to do that. Ultimately, we could no longer wait for the addict to make us okay. We had to find that on our own. You can, too. But this is the beginning of a long road to travel. This is part of your maturing and your growth. It is up to you, not the addict, to make the choices which will bring you safety and security and dignity. As codependents, our path lies in learning how to face reality and deal with it.
For now, today, you are very tired. Your vital force is spent. Get some healthy nutrition in you tonight, a warm bath, a long sleep, and if you have a friend who can come sit with you, call that person.
Today is only part of your story. There is more to come.
