Half of marriages fail.  I believe this is due to misunderstandings when it comes to what love is.  This webisode of Marriage 911 introduces the subject of real love.  This is part one of several.

4 Love is patient, love is kind, and is not jealous; love does not brag and is not arrogant, 5 does not act unbecomingly; it does not seek its own, is not provoked, does not take into account a wrong suffered, 6 does not rejoice in unrighteousness, but rejoices with the truth; 7 bears all things, believes all things, hopes all things, endures all things. 8 Love never fails;
