Hello Emma there is a forum dedicated to support for friends and families of gamblers on this site. (This forum is specifically for supporting the CG’s ( compulsive gamblers)).If you go back to the main page and click on the F+F tag it will take you there.
I know that the people who do use the F+F forum get a lot out of it and find it very helpful and supportive. Hope you find it.
Geordie.
