Is my wife the A**hole?

I am disappointed with my wife. We have a 2 month old daughter. She was born with health issues. But I still love my daughter and I will do my best to take care of her. I will never give up on her. My wife wants a healthy child with no issues. My wife said to put our daughter for adoption and we can adopt a healthy child. I said no. My wife said if I don't agree with her she will divorce me and leave. She told me I have to be a single father.
