I believe he did many great things. But even the Greatest, most Admirable man has his flaws. Haven't seen one that was perfect yet. I guess that goes to show us how human we all really are.
This is the info I found.
Previous Marriages:
None. However, while at Crozer Seminary, Martin fell in love with a Caucasian woman.
They talked about marriage, but after being warned of the difficulties of an interracial relationship and the possible negative impact on his career, they ended the relationship. King was described as a "man of a broken heart--he never recovered."

Martin's Alleged Extramarital Affairs:
Since 1989, when Reverend Ralph Abernathy wrote about Martin's adulterous relationships, the question of whether or not Martin Luther King, Jr. was unfaithful to his wife or not is still being debated. A year before he died, Martin allegedly revealed a longstanding affair to Coretta. However, Coretta stated that she and Martin "never had one single serious discussion about either of us being involved with another person."

King described his affairs as "a form of anxiety reduction." Martin said, "Iâ??m away from home twenty-five to twenty-seven days a month." Three relationships were more than one-night stands, and Martin grew especially close to one woman. The "relationship, rather than his marriage, increasingly became the emotional centerpiece of King's life, but it did not eliminate the incidental couplings that were a commonplace of King's travels."

Ralph Abernathy: "Martin and I were away more often than we were at home; and while this was no excuse for extramarital relations, it was a reason. Some men are better able to bear such deprivations than others, though all of us in SCLC headquarters had our weak moments. We all understood and believed in the biblical prohibition against sex outside of marriage. It was just that he had a particularly difficult time with that temptation.
