AITA for Refusing to Co-Sign My Sister’s Mortgage After My Parents Went Behind My Back?
She has poured years of hard work and sacrifice into building a future she can call her own, only to have her dreams threatened by a family decision made without her consent.

Caught between loyalty and self-preservation, she faces a heartbreaking choice: protect her financial independence or uphold a family bond that now feels more like a chain.
The love she once trusted is tangled with guilt and expectation, leaving her to wonder if family truly means never having to say no.
