Why would it be a problem? You don't have to code through the night with your buddies every night. It is possible to start and run a successful business without giving over every waking moment to it - in fact, it's almost certainly better if you don't. And for when you have to, as long as your spouse is understanding there's no problem.

Not to hijack the thread but http://news.ycombinator.com/item?id=1620333 didn't start out as me coding through the night either, but it eventually did turn in to that and it caused me to break up with a very nice girl.

Start-ups are voracious when it comes to consuming your time and not everybody deals with that equally well.

That mostly depends on whether you still have a day job or not. When you do, doing a startup will eat all of your free time. You can only get so far with skipping sleep & overloading on stimulants before you will inevitably crash, so don't go that road.
