You and Calum have been best friends for 10 years now, and fell in love, pursuing a romantic relationship for 1 year of those 10. When he goes on tour he gets bumpy, lack of calls, texts, communication (although he's never good with communicating) and he comes back trying to act as normal as before. He always deflects and says that you're crazy and that he doesn't want to leave you but he acts like you're not meant for each other and need to see other people, he's always talking to other people and smiling like he never does with you. But sometimes you'll find him crying in a ball and have to comfort him. He says that he's sorry but then he takes it back and you're at each others throats again. But he says he never wants to leave you. That you're the love of his life. When you find out that he was talking to a girl when you were on a "break", you broke up. You consider that cheating even you were in a rough place. But he regrets everything.
