Relationships are hard. Once the "newness" or "honeymoon" period wears off, you have to find ways to fall in love. We know this from studies and watching reality television. So watch out!
There's a new scourge that is causing relationships to flounder, marriages to crumble and chaos among co-habitants. Usually people break up over money. This is something that's deeper. It's about what you want and when you want it.
It's not about food, it's not about sex, it's not about power, unless that's the plotline of the movie you're watching.
