Marriage based on lie

What to do if before marriage a girl's family is told about so many lies? 1)During first meeting when boy nd girl was given time to talk, girl told boy about her past of unsuccessful engagement, and when asked same from him ,the boy refused about any relationship,but later on after 2 month of marriage the truth reveled about affair of husband with married lady which remained near about 3-4 months when husband accepted and stopped it then the girl forget and forgive him, But on the same day she came to know about two more lies which were about age and consuming alcohol. Girl specialy asked on the first day of meeting whether the guy drink or not ,again he refused,actually after marriage he continued drinking in small amount which confused wife and always were in doubt about boy drinking ,but after two months ,when husband came late night over drunk and made everything clear. And when this truth reveled ,his amount of alcohol is increasing without a gap for 7 months,comes late night,but never use any abusive language for his wife,morning he behaves like nothing happened previous night, for girl it's not acceptable at any cost as he drink and drive also and playing with his health and life.7months has been over by giving one -one month to stop alcohol. Another lie was about age ,according to boy family ,both age difference was 4 months,but in actual it is 6 years. The girl is ready to forget everything except alchohal ,bcoz it's not good for health, already told by wife to go take doctor help but not willing to leave alchohal... husband and his family otherwise nice.please suggest what to do,bcoz wife don't want to spend whole life with alcoholic husband???
