There's a reason your family thinks he's an asshole. Cheating on you more than once makes him one.
A one time thing is a whoops, a mistake. More than that is a problem and that just makes him a dick.
Just as we advise a hundred people here a week, you could potentially move on from your husband if you needed to. Is that the right choice? Who knows?! You're not at that point but you are a strong person INSIDE and you've got a whole bunch of people here backing you up. You've got therapy, you've got us, you've got people in your life. We're gonna support you in anything you do.
We're all waiting to hear what happens. Sending you good vibes and well wishes.
