is she fukn 16 yrs old or something??
Tell her straight out (if u wanna b in a serious relationship) that "no-one is going to be in 'command' of this relationship... not me, OR you, i dont order u around, and u dont order me around, ill give advice just like u should, and we decide on each others opinions on how much we agree or dissagree and how much it means to us"
hope this helps??
