i did the same thing......and i felt it was the right thing for me to do. he was draining all of our financial resources because he was in active addiction. he was irresponsible and inconsiderate of the basic living expenses....his only concern was getting money to drink and rent motel rooms to isolate and drink.
it's all about consequences for me.....the consequences of his behavior and actions resulted in him not having access to our accounts so that he could finish destroying our financical situation.
don't worry about it....you did the right thing....imo
