Answer:
Feeling numb
Step-by-step explanation:
Harley might feel numb after Dakota rejects his proposal and breaks up. The feeling of numbness will arise in Harley as a defence mechanism against pain. In psychological studies, many people have been seen to be emotionally numb after they experience an emotional pain like betrayal or rejection. They numb their feelings so that in the future they avoid such kind of pain again. Hence, numbness is a kind of defence mechanism against emotional pain.
