Lesson # 1 for wives of Internet Startups: Your hubby-dearest has just embarked upon an addiction - very similar to gambling...get used to it!
The wiki definition states "addiction is used to describe a recurring compulsion by an individual to engage in some specific activity, despite harmful consequences to the individual's health, mental state or social life"...well there you have it - your husband!
Very little difference between the life you will live, the justifications you'll hear, the promises of "this investor meeting is going to be THE ONE".....just accept it right from the beginning, and the ride will be smoother.
