Should I ask for a divorce ?

I've been married 10 years. I do almost all the housework. I also earn all the money we live on (we save the money my wife earns). We have a 2 year old child. My wife very seldom shows any affection to me. The affection we enjoy is mostly when I initiate it. Athlough 90% of the time I am rejected. She comes from a wealthy family and hasnever had any hardship at all, whereas I have come from a poor family and a challenging childhood. Her mother complains about having to clean the house but has been retired since she was 30. My wife masturbates more than once a day (she has told me) yet we have approx once or twice a month). I really love her but feel like a doormat. I am staying in the relationship for our child as I would do anything for my daughter, as I am a child of a bitter divorce, and know how hard it is. We are finacially secure (all self earned) and I am happy to leave everything to my wife and daughter (over $2m) to secure my daughter's education and security
