“How exactly did you manage to clean the dishes wrong? You’re so stupid!”
Though the partner cheating (or thinking about cheating) is in the wrong, they are often also the one in the relationship trying to bring the other person down and causing issues, thanks to their own guilt over their thoughts and/or actions.
“Often someone who is cheating is feeling a lot of guilt,” says Bethany Ricciardi, a sex and relationship expert with TooTimid, an adult-only online store. “Your partner can easily take out this shame on you by making you feel bad about yourself.” If your partner has suddenly become more hostile and aggressive with no reasonable explanation, you might want to sit down with them and assess the longevity of your relationship.
