Hot N Cold

"I should know that you're no good for me," she said, starting to walk away. He started after her, reaching out just in time to brush his fingertips against her arm. She stopped, turning and glaring at him, clearly unimpressed. "It's over," she said, forcefully snatching her arm away, out of his reach.
"Please," he said, trying to hide the desperation from his voice. "Give me another chance, or,"" she said, seeing she was about to move again, "at least let me explain."
"What is there to explain?" she asked, arms folded across her chest, brow raised. "You're moody all the time Brady, and there's only so much of it I can take. I've had enough."
"There's a reason for it," he said.
She didn't move a muscle and neither of them said anything until she finally broke the silence. "Well?" she adjusted her stance so there was more weight on one foot than the other as she waited.

Here was his chance. Maybe the last. To explain, to tell her the truth. Yet, he stood there, frozen, silent.
"You're hot than you're cold, you're yes than you're no, you're in than you're out..." she took a breath. "But what gets me most is, you're up than you're down. I feel like I'm stuck on a roller coaster Brady,, and I can't get off this ride. " When she finally spoke, it all came spilling out like the lid had been taken off of a bottle and it was overflowing. "I should know that you're not gonna change."
"No, but I  can't help it, though I try." He finally managed to get out a few words. Her arms tightened across her chest. She'd give him a few more seconds, she decided, because she was kind.

He wiped his sweaty palms on his jeans, reluctantly but finally meeting her eyes. "Jen, there's something you should know." Here goes, he though, firmly gulping down his nerves. "I have bipolar disorder," he said, breathing a sigh of relief that he'd finally managed to get the words out. "That's why I'm always so hot n' cold."

As he met her eyes once more, any nerves that he'd had a moment ago dissipated completely. All judgement in her face had gone and her hard expression had softened. "Brady, why didn't you tell me this before?" she asked, stepping forward and touching his arm. "You should have told me long before now! I was starting to think the confident, bubbly you was an act to reel girls in."
He let out a small chuckle. "No. You met me in one of my 'up' phases Jen, but then I got stuck on a 'down'. I'm sorry yo had to deal with me like that so early on," he said, smiling at last. "But you have to know something."
"Mmm.." she murmured, leaning lovingly into him as they walked.
"You played a big role in pulling me up again."
