On the r/AmItheA**hole subreddit, one Redditor (OP) recently opened up about their older sister's life-changing decision. At 19 years old, she had to leave college to take care of a two-year-old kid their late father had with his affair partner.
The OP explained in the post that their family went through a tough time due to their father's cheating. While the OP still hated their dad, the sister forgave him. So after their father and his partner passed away in a car crash, the sister stepped in to raise the young half-sibling, making big changes in her life.
Now, she's realizing how hard it is to raise a child and has asked their mom for help sometimes. But she refused.

The person says it's not the mom's fault for not wanting to take care of her ex-husband's affair child, and they think the sister, who is 19, is responsible for taking on a kid without being financially ready.
