Alex and you have known each other for a real long time, and dating a few good years now. Settling down for real and marriage was a talk you two sometimes had, but never really got too much deep into it.
You lived together, shared the same bed and routine, you were practically married, just without all the ceremony and "wife" calling stuff.
Nicknames are something really important in your relationship. When you call her darling or love of your life and she calls you dear or her soulmate, that's something you two share and are not afraid of it. Even the most cheesiest ones like sweet cheeks or cupcake, your friends would always tease you guys about it, but none of you minded.
Today you guys decided to just relax together. None of you are in the mood for cooking so you decided to ask for pizza and some chinese food. Alex is resting her head on your lap as you make the call, you decide to prank her to see her reaction and "accidentally" slip out the word 'wife'. The sit up abruptly, looking you with wide, happy eyes and a goofy smile on her face. "Did you just call me your wife?" She asks in an excited and hopeful tone.
