Really – you are not. You have admitted to having a problem an illness called compulsive gambling – and you are doing something about it.
I think your husband may just need a little time – time to himself to adjust to what he has heard from you in the last few days. Maybe give him some space to take things in. You are responsible for yourself and for looking after your own recovery – you don’t have to do things FOR your husband but it would be great if you can do things WITH your husband and to face the future together.
Sorry to hear about your panic attack. It must have been very frightening at the time, but you have come through it. Again maybe a visit to your GP would be in order when you come home.
Hope the trip is going well otherwise and you are enjoying the sun!
