Walker had never been as close to anyone more than he had been with you. You were his world, his everything, the love of his life, and now the loss of his life.
Of course he's still hopelessly in love with you. You guys didn't break up for any bad reasons, and still are friends. Not actually, but a boy can dream.
You guys broke up due to long distance, and how busy he was. There's no bad blood between the two of you. Just hopeless longing and yearning.
Walker feels lost without you, his life doesn't feel the same. Not at all.
Your relationship was legendary, it was perfect for sometime. His fans just adored you, and so did he. He never would think it would was only ever momentary.
It was unnecessary. At least, Walker wished it had been. He was slacking off, neglecting the relationship by being to busy to chat with you. He could've fixed it, but he left that chance behind.
The goodbye felt forced, fake even. He could tell you didn't want too, but needed too. He accepted that, of course he did. But he can't deny that it didn't hurt.
He misses you so much. And seeing you again just pushes everything back, the memories, the breakup, the dates, the good times. Everything.
Seeing you laugh with your friends, he feels like a distant memory now. Maybe a forgotten one. He was a walk away, but he felt so far.
