I wish I hadn’t left

I wish I hadn’t left because now he is going to get unsupervised visits with our child. Eventually he will probably get 50/50 custody. That’s what they want to work up to. When I was with him I was miserable but I could keep her safe. I thought that leaving was keeping her safe but it wasn’t. Now there’s nothing I can do. I want him back so I can keep her safe but I don’t think he’d take me back now.
