This one is kind of a doozy, so strap in.

I'm (M19) living in a ~1,000sqft. , 3 bedroom apartment with 5 other friends. We are assigned two to each bedroom, and the shared spaces are the kitchen and the living room.

One of my housemates (M19) has continually been using the shared spaces as if it was his own. Now, I can't act like I'm perfect either, but this roommate has left countless dishes in the sink (up to multiple days), and refuses to move his plates and utensils out of the drying rack and into the cupboards. When I asked him about said issue, he responded that my roommate clears the drying rack weekly anyways, and that it doesn't bother him at all.

The worst part isn't the kitchen though; unfortunately, it seems that this housemate considers the living room to be his second walk-in closet. From the first week that we all moved into the apartment, he's left his giant bicycle underneath the bar-styled counter in our living room that faces into the kitchen. He said that he would ride the bike to school (about 3-4 miles away), but that bike hasn't moved an inch for the past 6 months (he commutes by car instead). And a couple months back, he brought a mini-fridge into our already tiny kitchen, explaining that he'd sell the appliance on letgo or ebay (the refridgerator is still here to this day). But the last straw for me was when he brought in a giant foldable table (the ones you'd find at catered parties), and plopped it into the middle of our living room. 

Well of course, most of us were quick to express our discontent at the move. The table was an eye-sore, and even though we could use a coffee table-sized... table for our living room (lol), that giant, plastic, unaesthethic monstrosity was just way too much.

I talked to the housemate about this, and asked if he could maybe fold it up and put it away. He then explained that he needed a place to eat his food. I explained that we already had a futon and a smaller table (maybe a foot and a half wide and 5 feet long) where other people ate, but he then said he needed a place to study and do work. I then pointed out that *he had his own desk in his room*, but even that didn't matter, as 'his roommate often used the desk'. He also argued that there was already another desk (for study use) in the living room, and no one would complain about *that* one (which was a desk for the two girls that lived in one of the bedrooms together, but they didn't have space for a desk in their room).

I was kind of done with words. I angrily washed all of the dishes in the sink (which were his), and then proceeded to put away all the dishes from the drying rack into the respective cupboards and drawers (which were also mostly his). I then came back to my room to talk to my roommate about the issue and to write my woes into this post.

The giant foldable table now sits alongside the wall between our futon and the entrance to the kitchen. It's a fucking eyesore and I wish it would go away. I've been talking to other roommates about possibly getting barstools for the counter or maybe another smaller, manageable coffee table, but to this housemate, as long as the new furniture isn't there, the table stays. Even as I write this right now, he's using it to have a snack and study for school on his laptop.

So Reddit, am I the asshole that is declining my roommate's needs for a table and extra space to eat and study? Because maybe I'm incorrectly associating his need for a workspace with his poor kitchen management skills. But in general, it seems like he's just taking advantage of the shared spaces of our apartment. What do I do to convince the guy that he should move his shit out of our shared space?
