My wife is always accusing me of cheating and telling me that I'm doing things she finds disrespectful even when I don't mean it like that. For example, she gets offended when I call someone at work "sweetheart." I wish I had a penny for every time she accused me of cheating on her. She doesn't, and never will say she was wrong. How do I get her to understand?
Why do I feel like I'm always wrong in everything in my relationship?
People often project their insecurities onto others. Has she been cheated on prior to your marriage, or has there been infidelity in the marriage? Would she seek therapy for her insecurities, and/or couples therapy? Also, something to consider is not to allow someone elses insecurities to become your insecurities. Do not allow their words to penetrate your psyche. Your worth is not based on others estimations of you.You may enjoy this videoSelf-Esteem & Worthiness Affirmations - Remember Your Worth and value
