Sometimes when your career hits a high note, your personal life seems to fall apart.  While Zooey Deschanel had an amazing year as a breakout star, her relationship with Death Cab for Cutie front man, Ben Gibbard, seems to have come to a bitter end.  According to People, the two filed for divorce, citing Oct. 31 as their date of separation.  The ex couple, who married in 2009, are claiming irreconcilable differences, but are still on friendly terms.

How do you know when your differences are irreconcilable?

Cupid’s Advice:

Irreconcilable differences is the most common reason for divorce.  If you and your partner just aren’t the same people you were when your relationship began, you may be experiencing irreconcilable differences.  Here’s how to tell:

1. Always fighting: If you’re always arguing with your partner over both big and little things to the point where you agree on absolutely nothing, perhaps, your differences are irreconcilable.

2. You want to see other people: If you believe that you or your partner would be happier with someone else, it may be time to move on.

3. You’ve tried everything: If you’ve tried couples therapy and everything else to try to reconcile your relationship, but nothing seems to work, it may be time to cut your losses.
