I have twin stepdaughters who are 14. I love them which makes disengaging so hard. My dh says he always wants my suggestions and input as I have my own bio teen girls and want to help him with his as much as I can. We do our own disciplining of our own bios  of course. We've been married for a year and a half. My SDs bio mom has never been in their life. They were raised by dh and his ex wife who my SDs say was so hateful to them.
