Guy im dating is much older than me. So I was tired and he was like, "awww my little girl is tired"... he always says girl when he talk to me. What is wrong with him? So I called him little boy... and he said why I got to be a little boy.
A person cannot know which pet names or nicknames their partner likes to be called unless they are being told. I don't like to call my girlfriend "baby" for example, but some girls like to be called that. Just tell him you don't really like it.
You are still a grown woman no matter how much older he is. That sound sick when he say that like you are his daughter. But, at least you called him a little boy so he could see how it feel and hopefully he can call you babe or by your name now.
