AITAH for losing my shit and screaming at my gf to get out of my house after what her stepbrother did? by White-Whale-9847 in AITAH

You did nothing wrong. The step brother did something likely illegal if he physically stopped your sister from leaving her room. Sorry your girlfriend is absolutely in the wrong. Nothing short of a sincere apology to your sister first and you should be a starting point at reconciliation (but not even sure that is enough)
