Before founding eHarmony, Warren spent nearly 40 years as a psychologist specializing in marriage counseling. In his experience, whether couples stay together or split apart depends on whether they have what he calls “broad-based compatibility.”
.. One of the most important things for a strong relationship, Warren said, is that both partners are mentally healthy, and do not have disorders such as bipolar disorder or severe depression. In a 2014 study of the spouses of 60 patients with depression and 65 patients with bipolar disorder, members of both groups reported high levels of burden. Spouses of bipolar patients reported much lower satisfaction with their sex lives, too.
