What's the problem with your husband knowing about your side activity, as long as you strictly follow the observations he mentioned to maintain good practice in gambling? Of course, depending on your country and culture, tastes, opinions and marital issues may be different.

But do you like it or do you do it for profit? Well, it doesn't matter much, but is it bringing you a positive financial result? Even if you participate in campaigns here on the forum? What's wrong with him knowing that? I think women should also have their hobbies, tastes and opinions.
