I dont think confronting him will do any good, do you? Most likely he will say it is not his. I think what is more important is how YOU are feeling and what you need to do to make yourself feel more at peace and not so hurt and angry. We know we cannot change them or make them want to have recovery so you have to put the focus on yourself and do what is best for you. I am so sorry you are going through this. MY son has recently relapsed again and our relationship is very strained. We can only take so much. Hugs.
