Hi Gino,
Welcome to the Forum.
It’s so bloody hard being parents to someone who is an addict. I am the Mum of an addict (alcohol and cocaine), I sometimes wish I could forget about it all, but that would be far too easy. As you say there are so many parents in the same situation, I find it all very very sad. The sad thing about it is that it is only the addict who can decide when they need help, until they do this there is the life of hell living with them.
There is help out there once they decide to reach out.
You can speak to the Icarus Trust who will know exactly what you are going through. Read the Theresa thread on here, there is about 6 Mums all with Sons who are addicts, I find it very helpful to read the other stories.
Most importantly take care of you and your husband, having each other for support is a good thing.
Keep in touch on here, take care.
