I don't agree. If it is his money, it is his money. If it is her's, it is her's.

Can't tell what is truly happening here.

I find it strange to say that the partner who has the money is abusing the financially dependent partner by giving or withholding money.

So what he did was take back the money that was stolen from him and lie about it? So should he have admitted it and told his wife he thinks she is a thief.

I also find it hard to believe you don't know if he took it back or not. If $750 euro was taken from your hotel room and he is cheap, he would react completely different than if he had taken it back himself.

Stealing money again and hiding it somewhere else, now that's not going to help either.
