Relationships are "easy"? Gimme a break...

I read this somewhere, some relationship "expert" saying that healthy relationships should be "easy" -- seriously?? I mean, yes, a healthy relationship shouldn't be filled with unnecessary drama, and both partners should be mature enough to own and manage their own "stuff," not play games or manipulate or point fingers -- but even the best relationships are messy, all have their challenges and bumps in the road and misunderstandings that need to be worked out, and sometimes it's NOT easy... The assumption of a happily-ever-after, problem-free connection is a lot of bull crap, as far as I'm concerned. It's a fantasy that only leads to disappointment.
