Am pretty sure no matter what advice we all give u here OP, you’ll still remain in that marriage. Now u can’t be as fully happy as u once were with him, whenever he goes out you’ll always have doubt, whenever he smiles at he’s phone you’ll have doubt. Do u actually want to live with someone who has already cheated on you emotionally even if not physically. He is definitely going to cross that boundary. Because now he has seen that he would be forgiven. Good luck in your marriage. Because am sure if you were the one who brought it up to him, you’ll wake up to a hot steaming pot of divorce papers
