I agree. Put your family first and communicate with him about how you feel. It’s obvious trust was lost, but considering you have kids it may not be worth giving up yet. Make sure he knows about how you feel and let him know he has to choose between his family or his own adventures. Make things clear to him that you have no other options but to leave if it happens again and make sure to act on it or else he’ll continue his habits and realize your too weak to follow thru.
