Repeating the words of talaaq to confirm the talaaq

Q:

1. My husband and I were in an argument over phone that lasted two hours. He was angry and wasn't listening but he claims now that he was angry but not insane. He said "you are divorced" knowing I was in early pregnancy.

2. I replied immediately in shock by stating "did you just divorce me? Husband said yes, I said "are you divorcing me!" Husband said yes.

3. My husband gave me a first divorce in 2015 but took me back.

4. My husband informed me the words "yes, yes" do count as further divorces & he thinks our marriage is over. My view is that they are simply confirmation of him saying "your divorced" and is considered one talaq and so there is a chance for us to reconcile.

Question - Please can you confirm whether the word "yes" "yes" are additional pronouncements of divorce or just confirmation of his first statement of divorce. Please can you give the answer in accordance with hanafi fiqh only with references and evidences of rulings as my husband will only accept this.
