Please check it out - there is a forum for spouses. Bulimia is very serious - and since obsessive-compulsive disorders can be related to eating disorders, it also makes me worry about his gambling - I know you think he has the gambling under control, but it sounds compulsive to me.
I've been through anorexia and bulimia with my own daughter, and know it is not something your H is likely to "just stop" on his own.
Medications (like Prozac) can help about 2/3 of bulimics (and people with OCD).
