Seeking advice - Arranged marriage - How to live with an awful husband?

[Jane Doe]

I am 22 years old. I was wed in an arranged marriage by my parents 2 years ago, and I am so unhappy in my life. My husband is not the type of person I pictured myself spending my life with. He has extreme, extreme anger issues. He gets angry and emotionally abusive more quickly and more often than anyone I have ever met. He works from home on his computer, so he spends literally from the minute he wakes up until the minute he goes to sleep either on his computer or playing video games. He does not love me - he is unloving, uncaring, very nasty and bitter to be married to me. I walk on eggshells every minute of the day now in my life because if I say the wrong thing, he will snap. Even physically he is not attractive to me. He is in the "obese" category and has very poor hygiene. He doesn't care about taking care of himself, or me. All he wants in his life is to play video games and see lustful things. I find myself spending my life being as quiet and obedient and out of the way as possible, but I am so unhappy. I am at my wits end and I don't know what to do. Divorce is not an option for me because we have a daughter together now, and I refuse to have to have time apart from her for custody reasons. We are in WA state, so the divorce laws are to split everything 50/50, including child custody. What can I do to make myself happier in my life?? Please help!!!!!!
