What is recrimination?

In a darkly comic way, recrimination means, "They deserve each other."

Recrimination is the claim by one spouse, who is being sued for divorce on certain grounds, that the other spouse is also guilty of marital misconduct. Thus, the fault by both parties essentially "cancelled out" the other. That is, if both the husband and the wife had affairs, neither of them could claim the fault of the other in order to get a divorce. They were stuck together in the marriage. As you can see, this result was less than satisfactory and really makes very little sense.
