Massallah pertaining to talaq

Salam & mashallah for such a service to humanity and muslims
I have two wives & my first wife fought badly with me on petty thing, I ran out of control with her & beated her and came out of house. I was irritated so much I uttered “talaq” thinking her.
Presently I am very distress and anxiouss. Since I did not take name of and only said “talaq” can you tell me according Quran, Sunnat & Fiqh of Imam e Azam Abu Hanifa rahimullah that who’s divorced.
