In this task you are given an anecdote, which recount a complex ethical situation. The question you are given is, has the author of the anecdote acted ethically? answer this question with "RIGHT" or "WRONG".
Example: My boyfriend (well just call him M) and I are creators on Instagram (he is also on TikTok). I'm a digital and traditional artist and in one of my classes we create t shirts and things (socks, lanyards, water bottles, stickers, you name it). I'm a big fan of putting my art on t shirts so I can sell them.

M wanted to make some posts for TikTok and wanted to use the shirt I made today. My one personal rule is that if the shirt isn't being given to someone else, then I wear it first (this is because I know I wont get it back. Ive made one other shirt that I've worn, and he wore it for a week and hasn't given it back.) So I told him no, because I haven't worn the shirt yet. 

M proceeded to complain about not having content to post, and how his IG post today didn't get any engagement, saying "of course you dont know, because you never look."

Am I the asshole for wanting to wear the shirt I made just once?
Example solution: RIGHT
Example explanation: the author requests is justified.

Problem: Sorry for the long post; it's complicated. 

I've been friend's with C for many years. I ran into some difficult times in a housing situation, and C and his girlfriend K offered to rent me a room. C had been dating K for about a year, and I was good friends with K as well. I was weary about cohabitating with friends, but they practically begged me to do it. We set some ground rules, rent cost etc, and one rule being that they were 100% ok with me having  girls over or whatever, (tenant/landlord law in the state forbids landlords from preventing a tenant from having guests anyway.) 

Fast forward a few months, I had to have knee surgery which put me off of work for 14 weeks. In this time I needed an incredible amount of help getting around ( I couldn't drive either) and the girl I was seeing was amazing at helping me. She would stay over on days when I had early morning doctor of PT appointments and help me whenever she could.
 The problem was, K did not like this girl. K is the kind of friend who thinks she knows what's best for you, so even though she had no discernable reason to hate her, she just did. One week this girl had to stay over about 4 nights in a row, to help me getting to appointments and we were also working on a large charity project for a children's hospital ( this was around the holidays)
I should note that this girl didn't shower here, we didn't cook or eat their food, drink their drinks or hang out in common areas. I/We literally stayed in the room I rented the entire time. 
About a week later I get this text from K:

"Hey, I don't have a lot of friends, but the ones I do have, I value a lot in my life. Part of the reason I probably don t have a lot of friends is because I don't like to bullshit or be fake. If there's something bothering me, I like to talk about it and resolve it. I know you've told me you've had bad experiences with roommates and I have too, trust me, but I really did mean it when I said that we will never have an issue, because we are all good friends. 
I'm going to be upfront because I don't expect anything less from you. Get your dick wet...i love sex and I don't feel like you should be deprived. But can (girl) just come less? She's there every single day, and we didn't really sign up for 2 roommates. My sisters will be here from dec 23rd till January 11th, and unfortunately we only have two bathrooms, so could she also please not come when they are here? "

I responded "ok" but I was actually hurt a lot by this. 
Like.. being accused of trying to move this girl in, when she had no property here and didn't cost them anything was insulting. Also they know I can't walk or drive around due to my surgery, yet assume she's just staying over for sex. Not to mention I felt like if I rent a room somewhere, I should be able to sleep with whoever I want in that room. 
I couldn't argue the point because they're the ones helping me out with housing, and I didn't want to put my friend C in the middle of this, but I felt like this was only said because K hated this girl. I started looking for a new place to stay immediately but it took 6 weeks. In this 6 weeks neither K nor C, or her visiting sisters would even acknowledge my existence. No one would talk to me or even make eye contact with me. Not to mention my birthday was during the time her sisters were over which made it incredibly lonely sitting in my room like a ghost in the attic. 
I moved out and haven't spoken to K at all since. C contacted me later asking me to apologize to K for "getting weird and ignoring her" after she sent that text. The thing is, I couldn't do it. I didn't want to be her friend anymore. Unfortunately it also cost me my friendship with C. 
TLDR: I rented a room with my friend and his girlfriend. They agreed before hand they're cool with me having girls over. Had a girl over too often due to needing help with injury/Charity work. Friend's girlfriend hated this girl asked me to not have her come over so often/ anymore. I felt like if I rent a room, I should be able to sleep with whoever I want in that room. Both friendships with friend and his girlfriend are destroyed. AITA? 

Solution: RIGHT
