What is the conflict between Mama and herself in " A Raisin in the Sun"?

Mama sees herself as head of the family and yet wants her son, Walter, to grow up. As a result, she is conflicted about how much freedom she can and should allow Walter. At first, she refuses to even listen to Walter and his dreams of the liquor store. Eventually, she relents and lets Walter have control of what's left of the money after she's put a down payment on a house in an all-white neighborhood. After Walter loses the money, she finally realizes she must support her son's decisions if he is to grow up. She says to Benethea that they must support Walter even when he's at his lowest. Eventually, her faith in her son is rewarded when he refuses Linder's offer and says, "He finally came into his manhood today."
