I love Dr. Buckingham's response to this letter. In relationships we sometimes think that lovey-dovey feeling is always going to be there - the reality is that's a definite NOT! I know from experience. It certainly does take work on both parties part to make a relationship/marriage work, and sometimes that work is HARD, but worth it if you want a sustaining relationship.
Ask Dr. Buckingham: Can I Thrive in a Loveless Marriage?
