AITA for giving away all my cousins stuff that she left at my parents house after she announced she will be paying my student loans.

My (20M) sister (27F) and I live in a different city than where we all grew up. We still have a lot of extended family there, and we visit on holidays and sometimes in between when we can (usually together). My sister has a husband and one 2 y/o son, so traveling is a little more complicated than it is for me. My parents live in a 3-floor house that has a finished basement floor. My sister and I used to share a room on the second floor when we lived there growing up, and my parents have both our old rooms set up the same they were when we moved out. <br><br> When my sister moved out, she gave almost all of her belongings away to her friends, and didn’t leave anything at her old room (which is how she wanted it). She is also strongly against her son staying at our parents’ house when they visit (long story short, my mom has a bad habit of spoiling him to death when they do, and it causes problems for her and her husband). <br><br> My (21F) cousin Laura is my age, so we have always gotten along, and both our families have gotten along for as long as anyone can remember. Laura is very close to my mom, and my mom has been her mentor when it comes to her career, and has even helped her land a great job in her career field. Laura has a long history of telling other people in our family that she wished my mom was her mom. So when she finished college, she asked if she could live with my parents until she found a place to live of her own. My mom was more than happy to let her, and even let her live there for free for as long as she wanted (the only condition was she had to share a room with my sister). Laura agreed, and moved in with my parents as soon as she finished college. Laura ended up staying with my parents for 2 years before she moved out. She moved out 2 months before COVID hit. During that time, my parents would insist that she pay rent to them, and she would refuse. They never followed through on kicking her out, and she ended up living there for free for 5 years. <br><br> During those 5 years, Laura was basically a part of the family, and my mom treated her like another daughter. Laura would go on trips with us, spend holidays with us, and she even came along with us when we went to visit family in other states. Laura was very close to me as well, but never as close to my sister, because my sister never really saw her like family. During those years, Laura would share a room with me when she visited. This was the same room my parents originally had set up for her to share with my sister. Once I moved out, Laura would insist on staying in this room as well instead of my room. Laura would often bring her friends to my parents’ house, and they would stay there. Laura didn’t really have anywhere else to stay, so my parents figured they would let her, especially since they were letting her live there for free. <br><br> Before Laura moved out, Laura told us she would be buying a house in a different part of our old hometown, which is a 4-hour drive away from my sister and I. That’s why none of us have visited her new home, and why she doesn’t come visit us anymore. After Laura moved out, Laura asked if she could leave some of her stuff at my parents’ house. All that stuff was left in the room my parents let her stay in (she refused to put it in the basement or anywhere else). According to my mom, she told Laura she could only leave stuff in the room she was staying in for only a month, and after that she had to either come pick it up, or my parents would throw it away. Laura agreed. Before the month was up, Laura moved into her new house (as far as I’m aware). After the month was up, my parents texted Laura that they were going to throw away her stuff if she didn’t come pick it up. Laura said she was too busy with moving so she could only pick her stuff up in two months. My mom said that would be fine, as long as she didn’t leave it there any longer than that, and Laura agreed. After those two months were up, my parents texted Laura again that they were going to throw away her stuff. Laura said she was now too busy with her new job to come pick it up. After that, my parents stopped communicating with Laura about it. Laura didn’t live with my parents anymore, and she had already broken the agreement they made twice, so they figured she’d never come back to pick it up, and they didn’t want to continue to try to reach out to her. <br><br> Around the time COVID started hitting, my parents’ house turned into a family hub. My aunt is a nurse, so she and her daughter had to quarantine away from her son when he got sick. Since she and Laura already lived together, they asked if they could stay at my parents’ house, and my parents said yes. My aunt and her daughter stayed in the basement, and her son stayed in the room my cousin was staying in, but with Laura’s stuff still in there. My parents moved Laura’s stuff to the side of the room to make space for my nephew. After they left, my nephew asked if he could stay there permanently until Laura came back for her stuff (he was 16 at the time, and figured it would be years, if not forever, before Laura came to pick up her stuff). My parents agreed, and said they would keep Laura’s stuff there as long as he promised to move Laura’s stuff to the side when he stayed there. After he moved in, Laura started coming to visit my mom every 2 months or so. Whenever she did, my nephew would move her stuff to the side, and put it back when she left. <br><br> Right before Christmas of last year, Laura told me and my sister she would be paying our student loans off when she turns 30 (in 9 years). I’m finishing law school, so I’m pretty deep in loans. My sister already finished college, but didn’t graduate with a good job, so she has a lot of loans too. I was told that all I had to do was email Laura all my loan information, and she would contact our lenders and pay them off for me, and that it would take only a few months. I emailed it to her, and she said she would send me an email when the payment was processed. After that, I didn’t hear from her again for months. When I would ask Laura when she was going to pay off my loans, she would refuse to answer me or my parents. She also stopped communicating with everyone in my family (even my mom). When I would insist that she tell me when she would pay them off, she would say that she changed her mind, and didn’t want to pay off my loans anymore. I was upset because I had already dropped out of law school, and was working a pretty bad job.<br><br> During my spring break, I was going to my parents’ house to stay for 2 weeks. I texted my nephew and asked if he would be staying in his room (Laura’s room) while I was there. He said he would be, and that he would clear Laura’s stuff out of the room for me, and he put it in the basement. I asked what made him decide to clear her stuff out, and he said Laura’s stuff didn’t belong there anymore, and that she didn’t contact him to pick it up. He said he asked Laura to come pick up her stuff, and she said she didn’t have time. I asked Laura myself to come pick it up, and she told me she was too busy, so I decided to give it all away to my nephew. Laura ended up coming to visit my mom a month later, and my nephew informed Laura that Laura’s stuff was gone, and she flipped out. Laura insisted that her stuff was still in her room, and that my nephew was lying to her. Laura went downstairs and found that her stuff was gone, and started screaming at my parents that I gave away all her stuff. Laura also started crying because she claimed some of the stuff I gave to my nephew was her sisters, and that she was going to get in trouble with her sister. Laura ended up leaving after my mom told Laura to get out. Laura refusing to talk to my parents, and is now telling all of our extended family that I stole from her. Laura also called me (as well as my sister) and told me that she was going to call the police and press charges for theft, and that she wants all of her stuff back. I told her it was all gone, and she told me to get it back. I said no, and she told me she’s going to call the cops. I told her to call them, and hung up. <br><br> Am I the asshole for giving away Laura’s stuff? I think Laura is the asshole for lying about paying off my loans, and then thinking it’s ok to leave all her stuff at my parents’ house for years. As for Laura’s sisters stuff, Laura’s sister lives in our hometown, so it shouldn’t have been a big deal to just go pick it up. Laura’s sister never came to pick it up herself, even after she found out it was gone. I think Laura’s sister is the asshole as well for insisting Laura get her stuff back when she lives close by to my parents’ house.
