Dear Looby. Like the others, I want to wish you and your husband every good thing at this important moment in your lives. We all look forward to hearing soon that all has gone well with the medical procedures and hubby is thriving. But as the others have said, it could be a significant time for ‘father and son’ too in other ways and my instinct would be to let your son know if possible and allow for this opportunity to be positive for you all. As Velvet says, we can think that the cg doesn’t really love or care about anyone or anything but their addiction, but somewhere inside is always a person who probably does care, but is currently unable to express it. And if your husband wants to make contact, that is a crucial factor, of course. Every good wish, Monique xx.Keep hope alive.
