AITA for going no contact with my sister
AITA for choosing to go no contact with my sister(33f)? For a back story I(29f) haven't had my sister in my life until 8 years ago. We reconnected after my grandfather's funeral. Four years later she had my nephew and decided to go no contact with my dad, whom I still had a relationship with. I was supportive of that even if I couldn't understand the reasoning. My father said he was just grateful we had reconnected and had a relationship as sisters. Unfortunately my father got ill in 2024 and passed away from covid. I told her he wasn't doing well and told her if she wanted to see him now was the time as he wasnt doing well(I wasnt trying to force her at all, she had mentioned missing him, I just suggested it), the day she decided to see him he had already passed, I was the one who had to tell her.
During the time period after my dad's death and leaning more on each other for support, my sister has had several jobs she's quit. She'll start a job and then quit within a few weeks and try and supplement her income doordashing or Uber eats. This has caused her and her fiancee(29m) who stays home to watch my nephew full time, to get behind on bills more times than I can count. Being a supportive sister I don't want to see my nephew struggle because of her mistakes I would frequently give her money for bills, groceries, gas and more. She also has full access to all my streaming apps and hasn't paid a dime towards any of that in over 2 years. She faced homelessness with her family during the beginning of the year but was saved when her fiancé family bought them a 22,000 trailer to live in. Afterwrds she went no contact with them for suggesting they better themselves for my nephew. I've mentioned to her that I plan to move to a different state with my boyfriend in a few years to be near his family. Flash forward to three months ago I let my sister know that once our 15 month lease ends, which doesn't even go in affect in October, it was may then-that we planned to move. It ends January 2028. Suddenly she started getting distant, making up excuses that I couldn't visit or see my nephew. When mentioning it to her after a month or seeing this and us not talking as much she claims she doesnt understand how we can have a relationship with me moving out of state and has to protect herself and my nephew from being hurt. The last straw was her telling me that the last time I saw my nephew, which was a two months prior to this, that I was on my phone too much add I hurt his feelings, but yet, she never sent me a message to let me know about this and just sat with how she felt. That was the last time we spoke and its been 5 weeks. Today I wrote a letter and mailed it to her letting her know I was done and she needed to do better for my nephew. She mailed my dad a letter when she went no contact so I thought it was fitting. I miss my nephew so much but it's taken a toll on mental health the way she's used me, I wouldn't know what our realtionship would be like. I thought we were sisters but I feel used and lied to by her. AITA?
