Chapter 1:

Buck sighed deeply wondering how on earth he had ended up in such a mess. He supposed it was really his fault. Or was it his fault? Wasn't it her fault? Hadn't she been the root of the whole problem? Hadn't all this started with her?

Five years ago. Buck had quite liked his life.

The internet and his boyish charm provided him with an endless string of women. Each one lovely in their own way, but nothing special, but he had no desire for anything special. He was young and this was his time to have fun. At least until she wandered into his life and everything changed.

The first time he heard her voice it was even and focused. The second time it was soft and concerned. The third time she was tentative, then a little affronted, but he smoothed it over to an amicable ending to the conversation. The last time they spoke before he'd met her, she had been crying. He'd decided then to abandon not meeting face to face, she had needed help, and he could control himself.

When he first met her, her body was hidden under loose clothing, but she was pretty. Her strawberry blonde hair looked soft as it fell down past her shoulders, her eyes were full of kindness behind her glasses. She was older than him, but he liked her immediately and he didn't really care. It didn't matter anyway, because he was not going to sleep with her. At least not then.

After that day – when he didn't sleep with her, it didn't take long before he abandoned the idea of only talking on the phone. They already crossed over several lines that fell under the 'more than friends' category on the phone. He wanted to see her. After one party, a Valentine's date that ended in her having to perform an emergency tracheotomy on him and a night shift under a full moon, they'd finally given in – and then he realised everything had changed.

He'd stayed at her apartment – he'd actually slept there. He'd woken up next to her, one of his arms wrapped around her waist. She was still asleep. He didn't make to get up, he didn't want to. He liked this. He'd never done this before, he usually couldn't wait to leave after sleeping with a girl, it sounded bad, but it wasn't like they had ever asked him to stay. He supposed she hadn't actually asked him to stay, but she hadn't asked him to leave either.

He was also immensely proud of himself that he actually still wanted to see her after having spent the night. He had been concerned that he would be over her once they had slept together. Hen had rolled her eyes when he told her about it. She'd pointed out that obviously he'd want to still see her, he somehow lasted long enough to get to know a woman before sleeping with her this time. She also pointed out he talked about her constantly, she clearly wasn't a one night stand.

For the first time in his adult life he was in a relationship – a real relationship. He didn't want to sleep with other girls, he deleted his tinder profile and he was happy. But then a few months later, her mother had died and she'd gone to Ireland. She'd left.

He tried to keep it going, and she had too at first, but her phone calls and messages got less and less and then she stopped contacting him altogether. Carla told him she still cared about him, but she was trying to work some things out. He had decided to end it, he wrote down everything he felt he needed to in a letter and moved out of her apartment that he had being staying in.

It was almost eighteen months after he'd ended their relationship that she finally returned. For a moment, he saw her and felt joy, after not seeing her or hearing from her for so long, suddenly there she was. Then he noticed she was bleeding and he'd wanted to have her checked over, but she'd struggled and screamed that she needed to find someone – her fiancé. He felt like he'd been kicked in the stomach – hard. It took him a moment to process it. She had moved on. She left him and moved on. But then he'd written her that letter, breaking up with her. Of course she had moved on. Why wouldn't she have moved on? She was attractive, intelligent, loving and amazing. It was unrealistic to think she would be stuck for offers.

But she had ruined him for other women. He had thought after she'd returned briefly and tried to explain what had happened, he would finally be able to move on. He had moved on. Two months after that he'd met Emma. She was fun and sexy. She was a realtor. Maddie and Chimney had been looking for a new place together and Buck had gone with them to look at a couple of houses. This had of course been suggested by Maddie who had already met Emma at previous viewings and was just looking for a reason for Emma and Buck to meet.

They had hit it off and exchanged numbers. They went on a few dates and they soon fell into a relationship.

Things had generally gone really well to begin with. They got on brilliantly. They had so much in common. They liked the same films, bands and foods. He believed he was in love with her and after five months they moved in together. He'd been so sure about Emma, that he had found the one, that he wanted to marry her. On their one year anniversary, he took her to a beautiful French restaurant for a romantic meal and then they had walked along the beach in the moonlight. He had gotten down on one knee and proposed. She cried tears of joy and accepted. He was so happy. He was over Abby.

And now, here he was a month before his wedding in a complete mess. This weekend had been his bachelor party. Eddie and Chimney had been mostly responsible for organising it. They'd gone to Vegas for the weekend. On the Friday night, they'd hit it pretty hard at roulette and slot machines. There had been a lot of drinking and later in the evening, they'd convinced him to go to a strip club. The Saturday night was lower key. They'd gone out for one last dinner as just the guys. There had still been a lot of drinking, but they'd gone back to the hotel after. Most of the guys headed for their rooms, but Eddie and a friend of Buck's from high school; Chase had convinced Buck to have a nightcap (or three in the hotel bar). Eddie had retired first after two drinks. After his third drink Chase stood up.

"Come on man, aren't you tired? Let's go up, we got a flight to catch tomorrow." He'd said.

Buck had been looking over at the bar, it wasn't busy, there were still a few people dotted around, but it was getting later. He looked down at his drink.

"You go ahead, I'm gonna finish this and then I'll head up. See you tomorrow bud." Buck had said.

Chase had given him an odd look but left. Once he was out of sight, Buck had stood up and headed over to the bar, sliding onto a bar stool next to an attractive woman with long strawberry blonde hair.

The events after that became increasingly fuzzier. He remembered that they'd talked for a while. He remembered riding the elevator with her.

When he woke up, the first thing he felt was the pain in his head. The second thing he noticed was that he was naked. This wouldn't usually have been much of a surprise, except he didn't sleep naked in hotel rooms that he shared with his buddies. He then became aware that he was not alone. His arm was wrapped around a very warm body, the length of the body was tucked against him. He opened an eye and then the other. He was not in his hotel room, he was in a bed, naked, spooning an equally naked Abby Clark. Images of last night came back to him in flickers. He'd cheated on his girlfriend. He's had sex with Abby. This was a total mess.
