There are certain lies couples believe and they better should not. Like these:
Lie #1: The purpose of marriage is to be happy
Lie #2: My spouse can completely meet all my needs
Lie #3: My spouse is a bigger mess of a human being than I am
Lie #4: I am entitled to my spouse’s love
Lie #5: Our marital problems are all my spouse’s fault
Lie #6: My spouse should accept me just the way I am
Lie #7: My spouse should be just like me
Lie #8: I see my spouse for who my spouse really is
Lie #9: My spouse has to earn my forgiveness
Lie #10: We can reconcile without repenting

And psychologist Dr Thurman is sharp and experienced enough to put some quite useful insight concerning every of these lies.
While I differ theologically from several points and could use different narrative (given the cases and/or the explanations) here and there, I must say I have found some areas of further development needed in me in all of the covered issues (smaller or bigger). And this is not a small accomplishment.
