Author's Notes: Sorry this took so long to get out, I usually don't like to post without having the next chapter written….I've had this finished for a week or so now, but I don't have the next chapter done at all. Just thought that ya'll should know.

'Here's my promise made tonight

You can count me for life

That's when I love you'

"Fine Harmon! Enjoy sleeping in your very cold bed tonight!" Mac yelled as she slammed the door to his apartment. He sighed and shook his head angrily, glaring at the door. He stomped over and dropped to the couch. He sent a quick thanks to the powers that be that Mattie or Jen wasn't home tonight, or he'd have a lot more to deal with than one very pissed off Marine.

This wasn't their first fight, not by a long shot. They'd fought over smaller, petty things, such as where to eat one night, or whether or not Harm should keep a spare uniform at Mac's apartment. But nothing close to this magnitude.

He couldn't even remember what brought it up, and he wished now that he could take back whatever he said. And he was pretty sure he started it, because he had this horrible habit with pushing all of Mac's buttons at once. They had ended up arguing about their relationship, with Mac wanting to come clean about it, and Harm still wanted to keep it a secret.

They both said things that they knew they'd regret in the morning, when Mac finally had enough and stormed out of the apartment. An air of finality hung in the apartment, and Harm really didn't like it one bit. He looked over to his car keys hanging near the door and debated about going to her apartment. But then he decided that if she really wanted this, she would come back.

He padded off to his room, hoping to find peace in sleep. God he hoped she came back.

He woke up a few hours later, out of the blue and took a look around his apartment, getting the feeling that something wasn't right. There was a lump on his couch, a lump that looked strangely like one Sarah Mackenzie. He threw off his comforter, and walked quietly over to the couch, careful not to wake her.

Turns out that he didn't need to be quiet, he realized as he got closer, since Mac wasn't really asleep. She looked up at him, and he was shocked to find tears in her big brown eyes. "I'm sorry." She whispered. She sat up and made room for him on the couch. She began crying quietly and Harm quickly sat down beside her, and took her into his arms.

He held her close as she cried into his chest, her warm tears wetting his skin. Harm was confused as to why Mac was acting like this, she'd never been one to cry easily, and it worried him that she was doing so now. "Mac, sweetie, what's wrong?" He asked quietly, still holding her tightly.

She looked up at him, sniffling, and wiped furiously at her tears. "I'm sorry Harm, I shouldn't have stormed out like that…..I should've stayed and….God, I'm just so sorry Harm." Harm shook his head and gently wiped away the rest of her tears.

"Mac it's okay. You came back didn't you?" She nodded silently, and looked up at him. There was a very distinct pain in her eyes, and Harm hated to see her like that. "There's more isn't there?"

She nodded again, and took a deep breath. "Harm…I was driving around, after I stormed out and…" She swallowed slowly, trying to gather her thoughts. "God Harm, I felt like I was doing the same thing she did."

It took Harm a moment to realize who she was talking about. "Your mother?"

"Yeah, my mother. I just felt horrible when I realized that I just up and left without even trying to work things out….And this little voice in my head just kept on telling me that history repeats itself, and God Harm….I didn't want to be like her. I couldn't be like her." She sniffled and looked towards the window, away from him. "So I came back, and I've been sitting here trying to think of ways I can make it up to you."

Harm just shook his head, and gently cupped her chin, turning her back to him. "Mac, you're not your mother. I'm not your father, and I promise you I never will be. I love you Sarah Mackenzie, and nothing that you can say or do will ever change that."

She sniffled and looked up at him, sadness in her eyes. "But what if I am like her Harm? What if I'm doomed to repeat their history?"

Harm gripped her shoulders firmly. "You're a different person Mac. You can make your own decisions, and you won't end up like your mother unless you want to." He kissed her forehead lightly, and gathered her in his arms. "We aren't your parents."

They sat in silence for an hour before Mac finally spoke up again. "I promise that I won't ever leave you Harm. Even if I storm out in the middle of a fight, know that I'll always come back." She kissed him gently, wanting to make sure he knew what she felt for him.

"I know. And I want you to know that I'll always be here when you come back Sarah."
