Is it normal for this to happen?

Ever since my breast grew more when I was little my mom would pinch my breast and leave me painful bruises! At times she grabs one of them and squeezes it and kind of jiggles it around! I always had breast cuz I am fat and well it still hurts even if you are fat! She doesn't understand when I say STOP IT! THEY HURT! She still grabs them! She says that it is my period but it never is my period! if she applies pressure it hurts! But my nipples don't! I am 14 and have traumatic moments with my mother doing that and still do! I don't think even in the future when I get married that I won't let my own husband touch them! PLZ HELP!!!
