My dad disrespects my mom? its affecting me?

he doesn't like hit her or anything but kind of really disrespects her a lot and usually infront of me and my brother

dont get me wrong he is a good man and a good parent, very good. but its just this thing
and its kinda really affecting me :( beides the extreme stress when i hear them argue (or when it gets heated up) and when my brother starts to actually act like him sometimes (he is not a kid he is 21..)
its really affecting me with men
and i get scared what would happen when i get married :( will i be like her? will i stand for myself? will someone respect me? will i be overly defensive and drive a good man away? :(

its really depressing me anybody been there before? help?
