I was married in Portugal, always encouraged my wife to work and seek her financial independence, but she always refused. Now she wants alimony.

I was married in Portugal 23 years ago. In 2005 we moved to the US and became a permanent citizen. My wife works under 1099 rules as a court interpreter, an activity that I encouraged her to get into. During our whole married life, I encouraged her to work and become financially independent. She always found excuses not to, or when she has gotten a job, although she was always a good worker, she did not stay long, preferring to stay at home with our two daughters, a decision that she usually took unilaterally. She has a law degree from Portugal, which she can't use here, at least, to practice law. I have also always encouraged her to go back to school here in the US so that she could do a JD and practice here, or some other type of course, but she has also refused to. Now that we're talking about divorce, mostly because we have just drifted from each other, have little and irregular intimacy, she want alimony, which I don't think is deserved. What can I do to avoid paying alimony?
