Husband has become a a dirt bag

Husband is locking himself in office every chance he gets. It’s clearly either to master bate to porn or video chat. I know he likes jerking off. And has a mild porn addiction but it’s become so frequent that he literally will make the smallest deal onto a fake fight just to go master bate He says isn’t but I know he is. Anyone else dealing with a chronic master bater. Not sure what to do it’s so deeply hurtful.
