he screenshot me?!?

I was in class with my friend and we took a picture together and she put it on her story or something and he screenshot it without permission. My friend to me immediately and we asked him but he didn't say anything. Next she called him out in the hallway and he ignored her and blocked her on snapchat and her phone number which he had done to me also. He also tries to go after every girl and he told people that we hooked up without telling me he told. I told my parents about when he screenshot me and my friend. They told me it's fine but I don't know what he's gonna do with it. In the pic me and my friend were smiling and she put a heart in it.
