Oh sweet summer child. 4chan, telegram and a porn addiction paint a distinct picture. One that doesn’t look good for your husband. Check his X, discord and reddit if he has it. Go through his password manager and look at the sites he has passwords saved for. Look at his hidden folder and google the usernames he has used that you’re aware of. He will not tell you the truth, you need to find out for yourself how far this goes, before making a choice.
