Lydia was seething; she had been known to lose her temper from time to time but even her closest friends knew this was different and a time to avoid confronting her. Anyone trying to lend their support was met with the same, "That bastard", muttered grumble from Lydia. The slim brunette had just found that her long-term boyfriend, Tom, had done the dirty on her with someone from her office that he'd been introduced to during a recent office outing. "That lanky piece of shit can rot in hell for all I care" was normally her next grumble. She had suspected him a couple of times of going behind her back but she had always shrugged it off, but this time a colleague of Lydia's whose integrity she valued had seen the two cosying up at a local bar a couple of days previously, and by cosy, I mean proper hands on. Her grumble normally progressed to "I'm going to cut his balls off for this one" at which point the friendly ear would caution against such drastic actions at which point she would turn her vehemence on the other party in the deception, her colleague Audrey, and the things she would like to do to that 'slut' although sometimes she would be referred to as 'that bitch'.
When Tom had called to extract his few possessions from her place, he had received her vitriol with both barrels and had barely escaped from the front door with his manhood intact. For days she was this wild beast growling and snapping at everyone that crossed her path. She knew she had to snap out of it, no bloke was worth this much grief even though she had invested a fair bit of time knocking the rough edges off him so that he dressed and acted more like a bloke and less like a lad.
She had found solace in her daily visits to the local Gym; it allowed her to work off some of her frustrations at the male gender, the punchbag especially so, but in fairness any of the kit was subjected to a vigorous workout. A sweat would ensure she was able to take a shower afterwards without resorting to punching the partition into the next cubicle.
Today was different though; halfway through today's workout she saw Tom's friend Niall on a nearby machine. She didn't know Niall too well but had talked to him when the group had met occasionally on a Saturday evening at a bar. Niall was tall like Tom but his dark hair sat in waves on his head and appeared to be naturally layered, his lopsided smile, while innocuous, was strangely infectious. Lydia left him in peace for a short while but a nagging voice at the back of her head couldn't be ignored and so she made her way around the intervening machines to stand in front of the exercise bike he was currently sat on. He smiled nervously and said "Hello, this is a pleasant surprise."
Lydia gave him a half smile and asked, "I'm guessing you've heard about me and your mate Tom?"
Niall gave an apologetic wince and answered "Well 'mate' is stretching the definition a bit; we exist in the same social circle, but yes, I heard what he did across you and fully understand you kicking his ass into the long grass. That sort of behaviour doesn't sit too well with me if I'm being honest." She did not looked too pleased He secretly hoped his answer had headed her off at the pass; Lydia pulled a face he couldn't work out as she crossed her arms. In fairness she looked good in the crop top and tight fitting leggings but he was hardly going to try hitting on her under the circumstances.
He noticed her tapping her right foot as she asked, "Do you mind me asking, when did you know and why didn't you think to warn me."
Niall offered his hands up in submission as he replied "There was a rumour circulating but a lot of those turn out to be BS. I only knew for certain when someone else in the circle had said how you had torn a strip off him but by then you already knew."
This seemed to quash her anger as her foot stopped and she fidgeted her stance "Mmmm, I'm sorry. I shouldn't have jumped down your throat."
Niall shrugged "For what it's worth I've always thought he was too smarmy and was punching well above his weight with you but it's the twenty first century; we're watched everywhere. Did he not think you'd find out about him, although I'd counsel that this is the perfect opportunity to find someone far better. Just give it time."
Lydia sighed heavily and dropped her arms to the side as her shoulders seemed to cave under the strain "I'm not sure I'm in the right frame of mind to be looking for someone knew."
Niall climbed off the bike and took her hand saying "Look, give it time. That time you're not looking for the next swipe right will come and hit you like a punch bag from the left. You can do a great deal better than him; we're not all shits like him. I'm afraid I stink and so must hit the shower."
Lydia had accepted his reply and decided to take on the punchbag to work out the last of her frustrations. That would have been the perfect workout until she saw her nemesis over by the rowing machines. Audrey of all people coming to Lydia's gym; the brunette's temper started to flare and she had stepped away from the punchbag ready to confront the slut but then Lydia spotted that the slut was there with a couple of friends. Silently she seethed while scrunching her fists -- she would happily punch the next person who had tried to be nice to her. Niall had done a reasonable job of calming her down.'Hmmmm, Naill' she pondered. It was at this point that there was a shriek of laughter coming from the rowing machines, 'the bitch can't even use the kit properly. Grrrrr' fumed Lydia.
