He was a great friend, so there’s no escaping the sadness. As much as I believe in the importance of a positive and grateful attitude, it’s ok to experience the pain when a relationship ends and I was reminded how grief is a physical sensation — a cold, and achy place in your chest. Clearly, the terms “heavy heart,” “broken heart,” and “heartache” come from this shared human experience. That kind of hurt is part of loving something deeply. It is not weakness to feel it.
