AITA for reporting my wife's family after discovering my signature on her brother's loan?

At 2:14 a.m., my wife texted from her mother’s couch: “Sign the guarantor papers by 9, or I’m taking our daughter and the account.” I replied, “Then explain why your brother’s loan already has my signature.” I forwarded the credit alert to the lender before she could delete anything. By sunrise, her family’s “fresh start” was under fraud review, and my wife wanted to come home before her parents found out why. ---------------🦖D - Stories🦖--------------- #reddit #stories #redditstories
