Throw-away account for privacy.
In May 2024, after a $5,000 apartment scam left me reeling in the Northeast, my sister (22F) and I (then 25F) decided to move in together for mutual emotional support. She was fresh off a breakup and struggling. For the first six months in my small 1-bedroom apartment, I covered everything: rent, utilities, life. We were best friends and had truly never been so close.
As we upgraded to a larger place, a pattern emerged: I, a STEM professional with savings, covered the lion’s share ($2,400 of $3,400 rent plus expenses), while she contributed a flat $1,000. I wanted to help her find her feet, but through her job losses and a brief stint in a pyramid scheme, helping turned into carrying.
The breaking point came when my boyfriend and I decided to move in together after I had been living with my sister for 1.5 years and had drained my entire life savings. To save her from having to return to the Midwest, I invited her into our new lease with a locked-in $1,000 rent + she would be responsible for her share of utilities and her pet fee, but still subsidizing her significantly, as my boyfriend and I could live for less alone. (For context, we are renting a much nicer apartment than before, with 2 beds and 2 baths for $3,400/month before utilities/fees) I initially offered to cover her $85 parking fee, but later rescinded it, realizing that paying for her car was crossing the line from sister to parent.
Since then, the house has become a war zone. She feels misled and 'replaced' by my boyfriend; I feel used and unappreciated. I am now 27, working full-time, and pursuing an MBA. My life has evolved from bars to travel and career goals, while my sister and I's relationship seems to function only when I am financially overextending for her. We are tethered to a lease until March 2027, and I fear that if we don’t find a resolution, I won’t just lose a roommate… I’ll lose my sister forever.
Edit: Before May of 2024, I had been living alone traveling across the U.S.for work. In May, 2024, my work required relocation to the North East. It was a dream of mine to experience city life opposed to the small <3,000 population town I grew up in, so I was initially really excited . This was disclosed to my sister that I would be living in the NE for the foreseeable future before she moved into my existing 1-bedroom apartment in August 2024.
Edit No. 2: We moved into our latest apartment in December 2025 and the lease ends March 2027
