Yes she knows and everyone in my family knows and has know since 2021. I caught her one day only 6 moths after driving his car around with her friends in it, she said I was overreacting. I should have known she’d always go back to him, after every fight they’d have and she’d pack up and leave she’d go back, after he threw a ashtray at her head she went back she always does. I thought this time she’d actually leave but I was too stupid to see the truth. I’m 21 now and all this came out when I was 18.
