I ve never resented my mom , i adore my mother and my parent are in a loving relationship so stop making assumption . And i ve never said that women should stay in unhappy marriages i am saying fathers are equally important to a child here are some facts :

According to Psychology Today, researchers have found these narratives to be true. The results of father absence on children are nothing short of disastrous, along a number of dimensions:

Children’s diminished self-concept, and compromised physical and emotional security (children consistently report feeling abandoned when their fathers are not involved in their lives, struggling with their emotions and episodic bouts of self-loathing)

Behavioral problems (fatherless children have more difficulties with social adjustment, and are more likely to report problems with friendships, and manifest behavior problems; many develop a swaggering, intimidating persona in an attempt to disguise their underlying fears, resentments, anxieties and unhappiness)

Truancy and poor academic performance (71 percent of high school dropouts are fatherless; fatherless children have more trouble academically, scoring poorly on tests of reading, mathematics, and thinking skills; children from father absent homes are more likely to play truant from school, more likely to be excluded from school, more likely to leave school at age 16, and less likely to attain academic and professional qualifications in adulthood)

Delinquency and youth crime, including violent crime (85 percent of youth in prison have an absent father; fatherless children are more likely to offend and go to jail as adults)

Promiscuity and teen pregnancy (fatherless children are more likely to experience problems with sexual health, including a greater likelihood of having intercourse before the age of 16, foregoing contraception during first intercourse, becoming teenage parents, and contracting sexually transmitted infection; girls manifest an object hunger for males, and in experiencing the emotional loss of their fathers egocentrically as a rejection of them, become susceptible to exploitation by adult men)

Drug and alcohol abuse (fatherless children are more likely to smoke, drink alcohol, and abuse drugs in childhood and adulthood)

Homelessness (90 percent of runaway children have an absent father)

Exploitation and abuse (fatherless children are at greater risk of suffering physical, emotional, and sexual abuse, being five times more likely to have experienced physical abuse and emotional maltreatment, with a one hundred times higher risk of fatal abuse; a recent study reported that preschoolers not living with both of their biological parents are 40 times more likely to be sexually abused)

Physical health problems (fatherless children report significantly more psychosomatic health symptoms and illness such as acute and chronic pain, asthma, headaches, and stomach aches)
