Jules should have hired the CEO right?
Sure she built the company and had lots of great ideas and insights. But she wouldn't be able to keep going like she did. It's not a work vs family question, it's her long term health. She didn't know how to delegate, she was constantly stressed, not eating or sleeping right. Sure, Ben helped her relax a little bit, but her resolution at the end was pretty much to keep everything in her life like it was.
I like the movie and I don't really mind the ending(though the husband is beyond meh) but it's definitely movie logic. I think if I was the intern I'd advised her to at least try the guy she thought seemed good.
There is no such thing as too much time
