“I just feel that our relationship’s entropy has increased.”

“Read this [second law, Simple Wikipedia] and this[thermodynamic entropy, Simple Wikipedia] before going further (Don't worry--they're in Simple English).

A relationship is a lot like a closed thermodynamic system. Starting off there is much potential for success, almost unbridled potential. You could have just found the person you were always meant to be with, and each new fact and intricacy of that person adds to that mystique. Entropy decreases.

With time, however, as in a closed thermodynamic system, entropy increases and heat dissipates. That's not to say that feelings do not get stronger, but the relationship can tend toward a sort of normalcy and complacency. The system needs an outside source of energy to push it onward and decrease entropy [see: entropy increase] once more.

But should that added, outside energy [see: coupling] be necessary? Is it worth the added energy to work toward something that will eventually even out once again? Or should people just accept the increased entropy, letting systems settle [see: equilibration] and relationships end?”
