Very true.
My parents always said knowing that you HAVE to work things out and divorce isn't an option actually made marriage easier, in some ways.
Marriage and love is an act of will...not always emotion. A true commitment endures challenges and heart aches. Some people have no commitment to their marriage...then they wonder why it didn't work out.
In addition, the marriage vows include the wording (paraphrased) 'not to be entered into lightly'. Marriage shouldn't be a Vegas whim..it's a serious decision. More folks should recognize that.
