Thought I could give a perspective from the other side of the street. I don't think I will ever quite believe it's forever because believing that strips away the defences should a relapse occur. That said, I would trust the longevity enough to have a child with my partner only after two or three years sober. That's not to say I wouldn't believe his good intentions or seriousness, but to stop worrying... Well that would take a few years for me.
