Through the Past

     It had been a year since Colby and I had a fallout, through no fault of my own we split, a web of miscommunication unraveled an he cheated on me. We had an argument, a bad one at that, he thought when I left to go out I scratched down the side of his new car with mine. Regardless of the true story Colby had it set in stone that no one other than I could have damaged his car because 'I'm the worst driver in California'.
     Thing escalated to a level that was unfamiliar coming from Colby, he the left to go to our favourite bar "Take the Piss" only to come home drunker than I had ever seen him. The unfamiliarity scared me and when he started getting aggressive, and breaking things, I froze, reverting to my old habits from bad relationships. I fled the apartment and stayed the night at Sam and Kat's place, they always made me feel welcome and it was a 'no questions asked' situation. After letting Colby cool off and sober up I went home just to find out Colby slept with not one, but two waitresses that night.
So I packed up my stuff and moved back to Utah wanting finish my college years on campus, hoping to take a little mental retreat away from the cali chaos. Although I left Kat, my ride or die since grade school because I thought the only solution to heal and forget what happened that night was to move hundreds of miles away to finish college.
I knew he wasn't the violent towards people type but my past made me scared. And if it's happened before with someone else it can happen again with someone new.
Colby and I didn't have a bad relationship so much as there was a lot very toxic traits to it, he would always flirt  with girls while I was with him, as if I wasn't there or wasn't his girlfriend. Not even trying to hide it as well. And he didn't trust me ever, he said I was 'too pretty to be trusted alone' which at first thought you would think is a protective thing, no, not with Colby it was a 'she is cheating on me' thing.
    And no one knew, neither him nor I made it apparent to social media that we were dating so me leaving didn't spike anything in their Youtube videos apart from that Kat's best friend moved away to go back to college and finish her classes. It was under the radar and no one knew so moving back didn't cause any suspicion.
Sam used to tell me that he was 'just being over protective' and 'he cares about you and doesn't want you leading him on' and I hope that deep down Sam knows he was just saying that to ease my stress but Sam is and was his best friend. So when Colby and I broke up and Sam and Kat didn't, they were distant from each other for a while because they were on different sides of the breakup. They got over it after I moved because they only had to hang out with Colby and I wasn't there anymore to make an uncomfortable situation.
I decided to move back to LA when I got a paid internship offering from an excellent architectural and structuring company. This company made props and stages and building for movies and tv shows. It was my dream to work on the sets and stage props for movies like Narnia or Harry Potter, and I was hoping that this internship would help me get there one day.
      I knew Kat would have my back and wouldn't oppose to me coming back. She was the one who encouraged me to move to LA in the first place as well and even got her dad to arrange me studying off campus, out of state really. She said she would find me an apartment and she would send me the address as soon as it was finalized. In all fairness she did, however.... I was not aware that I would be living directly above Colby and in the same building as her and Sam.
And let me tell you. this lunch was not the first nor last of mine and Colbys' odd moments of 2021. And to make it worse. Brennan, walked into the picture.
