Can I still get alimony if I was unfaithful in my marriage?

I’ve been married for 27 years and was a stay at home mom most of that time. My husband is from Turkey and has a high level job with the U.S. government in Washington, DC. He earns a lot of money but does not share it with me. He is very controlling and verbally abusive. After years of this I was very unhappy and had a relationship with another man who was kind to me and supportive. My husband recently found out about this and says he will now divorce me and because of my infidelity, I will get nothing from him. I have no college education and currently no way to support myself. Will my unfaithfulness disqualify me from receiving any alimony or other financial support from him? Will it make a difference if I can prove that my relationship occurred as a result of my husband’s abusive and controlling behavior?
