On the contrary. I think breakups hurt because/when you think about them. There’s definitely a time for self reflection but the best remedy might be cognitive distraction. Anecdotally I’ve found that investing time and energy into alternative forms of “pleasure” is a powerful way to extinguish “emotional pain”. Adequate and appropriate nutrition, exercise, hobbies, friendships, meditation and even medication (if necessary) can all work effectively. We need energy for emotional resilience and just being “hungry” can dramatically amplify the pain of a breakup.
