Terrified for my little girl

Long story short my daughters dad was useless and verbally and physically abusive to us. Me more then her, he would scream in her face and squeeze her arms sometimes. Sucks when you don’t have enough proof to protect your baby in court. Anyways her dad hasn’t seen her since sept. he has been doing therapy since sept for his anger issues and magically it’s okay got him to see his daughter unsupervised and guys I am terrified. I know she’s gonna fight him tooth and nail to not go in that car seat she does it to me when she gets in moods. Also bc of him my daughter gets so worked up sometimes she has panic attacks. Also he doesn’t know his own strength, I’m terrified she’s gonna get hurt or this will affect her in a different way going with a stranger who had barely seen her in a year. After I dumped on the beginning of the year he ran to a stranger 3 hrs away and abandoned his daughter for 3 months. I really hope it all goes well for her and nothing happens…😭
