Respect your wife like you'd respect your mother
Had a conversation with a younger guy about marriage and he was complaining about his wife in front of everyone like she wasn't there. Told him straight up that's not how you carry yourself as a man. You protect her dignity, you speak about her with reverence, you make decisions together. Marriage is a partnership and she deserves your best self. He looked uncomfortable but sometimes you gotta say what needs saying.
Real talk, the younger generation doesn't always get this. Marriage is a partnership and trashing your partner in front of people is just asking for problems. Good on you for saying something.
