According to the Game theory of male/female relations (correct me if I'm wrong), women tend to control whether a relationship is made or continued, and her decision depends on the guy's alpha-ness. She won't want to be in a relationship if the guy is too agreeable. If this is so, I would expect disagreeable men to be more likely than cooperative men to be married. The MIDUS study measured Big Five personality traits and asked about marital status. I dichotmized this variable into married (1) and not married (0). I looked at the relationship between the agreeableness scale and being married, and included age in the model as a control:
Logistic regression coefficients (sample = 1,788)
Older men are more likely to be married, but being an agreeable guy doesn't hurt one's chance of marriage at all.
I suspect that the Game perspective is flawed by oversimplifying. As we learn from evolutionary psychology, women tend to look at men from two different perspectives: as short-term and long-term partners. They tend to be more attracted to the Alpha for short-term relationships but focus more on the Beta for marriage. Betas are at a disadvantage if they just want to get laid, but their cooperativeness does not appear to keep them out of long-term relationships. (Nor are they more likely to lose a wife through separation and divorce: the mean agreeableness scores for married, separated, and divorced men do not differ.)
