What does it mean if a guy says "theres my girl" ?

He has also called me other names like cutie, pumpkin. We have known each other for a little while now and lets just say there was some history between us. We never got to the relationship part of things.

I keep telling him goodbye but i keep messaging him and he said "theres my girl" . He tells me he wants me to go but if he did why would he call me nicknames?
