Dominating the Roommate Game

user boyfriend and Rachel have been dating for about four years before this all happened. I honestly cannot believe the path I’ve spiralled down the last few weeks but… I want to share my story... I’ll start from the beginning. Bf and I were recent graduates, him from nursing school, me from my MBA program, and settled down into a new apartment in the city to build a life together. We had applied to dozens of jobs but, by coincidence, we both ended up getting a job at the same hospital — I was hired as an administrator and he, of course, as a nurse. I absolutely loved this man and he kept being even more amazing as time went on: he was kind, sensitive, an amazing listener, and just so in tune with his emotions — all of which were a breath of fresh air from the jerks and narcissistic assholes I’ve dated in the past. He won my heart over quickly when I met him while finishing up my MBA and we’ve been in love ever since. Our dream one day is to be able to put down a downpayment on a new house and so we picked a small apartment with cheap rent in order to save as much money as possible. The small apartment wasn’t the only compromise we made — we decided to choose an apartment that we could rent out to a roommate as well. My boyfriend reached out to a couple of his old college friends, asking if any of them were interested in the room, and, a few weeks later, one of them moved in. This brings me to Mike user's best friend. Mike has always been an enigma to me. I first met him when I started dating my boyfriend and, right from the get-go, there was always this odd discrepancy between how he treated me versus how he treated my boyfriend. Basically, he was really nice to him… but when it came to me, he’d immediately switch into this rude jerk, almost like I was beneath him for some reason. I eventually brought it up with my boyfriend and… well, now that I think about it, he was a bit shy and reluctant to tell Mike to be nicer to me … almost as if my boyfriend didn’t want to cross him or something… anyway, I always thought it was weird but decided not to make a big deal out if it because I didn’t want to be the type of girlfriend that started drama with his friends… After hanging out with them for a few months back in college, I started to notice how much of a womanizer Mike was. However, what baffled me was that he wasn’t just a jerk to me… he was pretty much a jerk to every girl he spoke with… yet, he never failed to leave the bars with a pretty girl under his arm… I commented on it to my boyfriend at the time — I remember him saying, “Yep, no idea how he does it but he’s never had a problem getting laid… I never liked having to hear his wild stories about the chicks he bangs, because, well... you know... I’m just not that type of guy...” and he kissed me, implying that he was the type of guy to only date one girl at a time and commit to them long-term — and I loved that about him — seriously, it was so refreshing to meet a guy that didn't run for the hills at the first mention of commitment... But... I’ll be honest... ... because Mike was such an enigma, he kind of had my curiosity piqued... ... like, how on Earth did he get so many women while being such a cocky asshole? Personally, I hated his attitude, and, when put into contrast with my sensitive, sweet, loving boyfriend, it made no sense to me that all these girls threw themselves at Mike… I mean, sure, he was physically attractive, but being hot is so irrelevant when the dude is an insensitive asshole. At least in my books... Well, fast forward to about a few months ago where Mike had just finished moving into our apartment... The only thing I had said to him was that he was only allowed to move in if he promised to never bring girls home. I made sure to establish that boundary as there was no way I was willing to deal with random girls being brought over to our apartment every night, nor did I want to deal with any loud sex coming from his room... other than that, I didn’t really acknowledge him much because, as you already know, I wasn’t a fan of him, and he was only there to help pay the rent anyway. To be honest, I didn’t give him much thought at all after he moved in since I was intensely focused on my career — as one of the new administrators that came in at the same time as a bunch of newly hired employees, I was already responsible for whipping some of the new people into shape. After the first few weeks went by, I really grew into the position, turning into this boss-bitch woman who took control of situations and got shit done. After the third week, everyone followed my orders without question, and, if you’re wondering why I’m telling you this, well, there's a reason... See, the hospital's HR made sure my boyfriend was assigned to a different team administrator due to our relationship status so he didn't know about my newly discoeverd boss-bitch attitude at work ... so, instead, he learned about it in the bedroom... Soon, whenever my boyfriend and I had sex, I was more dominant, more controlling and more demanding towards him… and, to both of our surprise, he lapped it up ― naturally falling into a more submissive role in the bedroom. It was exciting for me to evolve into this new sexual dynamic with him and, even though he never seemed to explicitly talk about it outside the bedroom, I could tell he was enjoying every minute of relinquishing control over to me as much as I was taking it.
