Plusha your dad changing part. I can kind of relate to it. But why would you wanna be in your mom's shoes for even a couple of years. Times were different back then. Don't know what your parents' situation was. But in most households emotional or physical abuse was not taken that seriously. Even the wives back then were more "sabar wali" & would stick around & take everything in because of their kids. Men do change but that's after 20-30 years when they are not physically strong enough or are not the only man in the house. Meaning the sons have grown up & even then if a person was physically abuses he changes but emotional abuse. Never. It NEVER EVER changes.
Its good to be hopeful. But be realistic at the same time. Good luck with everything.
