Which brings more harm to the other half, physical infidelity or emotional infidelity?

There is no greater harm to this problem. Whether it's emotional derailment or physical derailment, it's undoubtedly a great harm to the other half. Let's briefly analyze the reasons.

Physical infidelity, physical infidelity has nothing to say, there are substantive actions. Trust a person who tells you that he loves you, but sleeps with others affectionately. You don't believe that he loves you spiritually, do you? What's the use of loving you spiritually? Someone who gets your heart but can't get you? Stop joking, okay?

Therefore, a person who loves you, whether emotionally or physically, is unacceptable. Instead of discussing what kind of harm two people do to the other half, it is better to pay more attention to the reasons why you want to cheat, and then communicate with your partner to solve the problem and avoid this kind of harm.
