Massallah pertaining to talaaq

Assalamu Alaikum!
I issued one talaaq e Bain to my wife namely Salma on her request. After her iddah passed, I was going somewhere thinking her and was very irritated with her and uttered “Agar Shaadi karon to talaaq
Now I want to marry another woman namely Afshan, keeping in view my above circumstances and the sentence I uttered thinking my ex-wife Salma will every woman i marry be divorced or only Salma will be divorced on marrying.
Waiting for your reply anxietly.
