Infidelity, Alcoholism and Emotional Abuse

I am married to an extremely financially successful, professional, high functioning alcoholic who claims to love me but demeans me at every opportunity. I have forgiven his cheating with a coworker once very early in our marriage but have always had reason to suspect .....never any proof....until now... that he has continued to be unfaithful with a variety of women over the last 10 of our 14 year marriage. Together we have 4 minor children and a fair amount of property. I am a university educated stay at home mum. My husband consumes 10-15 drinks after work daily and passes out in front of the TV with a drink in his hand nightly. We currently sleep in separate rooms are seldom intimate. There is no physical abuse but I am always made to feel inadequate despite being a physically fit, intelligent, beautiful vivacious woman. I don't want to do this anymore....this recent proof of infidelity is too painful compounded with the physical neglect and emotional abuse. What am I entitled to financially and what should I do? I am just fed-up!
