What should I call my "boyfriend"

Roshelle
I quoted "boyfriend" because we never made that official, we're pretty much still talking but he calls be "babe" and "bae" and "baby girl" and I wanna call him something other than his actual name but I just don't know what to call him without sounding awkward like I thought of "papi" but that might be weird lol I don't really hear girls calling their mans that anymore and I wanna call him babe sometimes but I wondered if it'd be weird because he calls me babe. is it weird when a guy calls his girl something and the girl calls him that same name? Lol idk, what do you guys call your SO?
