This depends on his intention. If he intended to divorce, the divorce took place only once. If not, this was an oath that must be expiate by feeding ten poor people.

It is very weird that you ask for your own divorce like this!

My husband used to drink alcohol and when ever i ask not to do that he recite kalma that he will not do that again and then he go there again and consume alcohol repeatedly. Once I asked him that if he ever consume alcohol again , will i be divorced and he said yes if he ever do that again you get 3 divorces and after 10 minutes he went to alcohol party and consumed alcohol. is the divorce valid
