As a marriage and family therapist
(MFT), I see the same concept (the manner in which we maintain our cars) existing in our interpersonal relationships. There are couples that seek counseling before they even marry, to explore their unspoken expectations in the safety of a therapeutic environment facilitated by an impartial clinician. Equally, there are other couples that, deep inside know that something is wrong with the relationship, but choose to ignore the signs until someone does something very hurtful.
It is important to point out that “Only about one fourth of divorcing couples report seeking professional help of any kind to improve their relationship (Albrecht, Bahr, & Goodman, 1983; C. A. Johnson et al., 2001), and those who do, wait an average of 6 years after serious problems develop to seek marital therapy (Notarius & Buongiorno, 1992, as cited in Gottman & Gottman, 1999)” (Doss, Simpson, & Christensen, 2004, p. 608). While divorce may be essential and the appropriate choice for some couples, others may desire to try to restore their relation.
