What the fuck???? That dude needs to be stomped into the ground!!!
I understand how you feel, but whether she’s conventionally attractive or not isn’t going to protect her from bullies. Be honest with her. Teach her get worth. The best way to do that is through example. Think highly of yourself and she’ll do the same.
Teach her about power and control. Teach her red flags to look out for. Show her that her body belongs to her and only her.
She’s got a great mom. I see a bright future ahead for your little one!
