What is Mother-in-law?
1.
A son's mother - who after he takes a wife, becomes jealous of the wife and considers her competition for the son's affection (which is gross and somewhat incestuous). If not put in her place (told to fuck off) by the daughter-in-law immediately after marrying her son, the mother-in-law will grow fiercely competitive and attempt to wreck the son's marriage by whatever means necessary.
My mother-in-law is jealous of the fact that I married her baby boy and helped him to become a man. What a sick bitch.

A woman who bears children who one day wed, will find herself at the wedding day changed into a mother-in-law. This demotion of status as the previous Number One female in her children's world can create horrible changes in what was once a lovely woman. Most of the bad scenarios arise from a jealousy between wives and mother-in-laws, although there have been some husbands who have faced the wrath of a mother-in-law. A mother-in-law is generally seen as a mythically bad person. As a parallel, father-in-laws don't get the same bad rap.
New wife says, "I thought I married just my husband, but his mother is a huge part of our life!"
Therapist says, "Yes, she is your mother-in-law, and if you let her, she can destroy your marriage. Think - two women love the same man."
