You will wonder why your chest feels so tight whenever her name rolls over his tongue. Not me, but the other one. The one who will always have a place in his heart. Don't give up yet, but listen to every story of them. It will break you for sure, but you will know how once he loved someone that much. You will find yourself think about him continually. When you walk alone on the street, when you are with your friends talking about life, or simply when you wash your dishes. You will think about him in any places in any situations The thoughts of him will make your stomach churns, like you've been riding a roller coaster for so long Sometimes the excitement will put you on the top of the world but then reality will take you down, twist you around, and flip you over. Again. Don't give up yet. Bring him muffin or take him out to have fudge brownie ice cream on the weekend. Those are his favorites. Remind him to not sleep late because he will get tired and grumpy in the morning, tell him it is okay not to be perfect all the time, and the most important thing be there for him when he is unhappy with his life or when the memories of her keep crashing back to him. You might prepare a band aid for gashes that will be left in your heart. But please don't give up yet.
