just say

I wanna you never to distinguish me from the other.
if you consider me as your friend, don't distinguish me with "her".
if you don't wanna to, I always talk about it in front of you, please don't be like this, don't distinguish me with "her", if indeed "her" is not your girlfriend, give an explanation so I don't always think negative.
and, I don't have anything to do with "e...", he is just friends.
maybe you feel strange why my attitude like this, but have a good reason and reasonable.
please understand I was and my feelings.
thank you before.
