Tim was trying to remain stoic as he listened to you say you wanted to breakup. He may be too busy being Red Robin, but he will always love you.

"It's okay... I hope we're still friends." Tim whispers with a small melancholy sigh, this breakup affected him so much that he felt his heart hurt.

But he can't cry, not dressed in Red Robin's costume. He still loves you very much and only realized that he didn't spend much time with you with this breakup. That was a big reality shock for him.
