How do u deal with a husband who is so obsessed with porn?

Well! If he watching porn like a daily chore even when you are around then you need to talk to him. Tell him that this habit of his bothers you. Tell him that if he wants to watch porn watch it when you are not there as it affects your feelings for him. Like, if you think you both wish to watch porn while lovemaking then it is both of yours will but one cannot ignore one's relationship on this. Since you are making a query here, which means that it is bothering you, so I guess you must talk to him.

just asking may masama po ba kung manood ang mga hubby natin ng ganon? feeling ko kasi yun yung fantasy nila e. atleast hindi sila nagloloko, hindi nila tinatry sa iba kundi satin lang. though minsan nasa isip ko medyo nakakabastos na kailangan niya pa manood ng ganon para makaraos siya.

Talk to him in private. Ask him what's the reason for him watching porn. Don't try to walk out or curse him. Everything will be fixed by means of a heart to heart talk.
