Calling your SO or husband babe/baby?

Mary
I'm just curious because I doubt I'm the only one, but for some reason I have never been able to call my exes or my current boyfriend babe or baby. It just feels awkward. We have other pet names for each other, but I even struggle saying it in text! It just seems odd because I hear and read other people always calling their partner babe and baby. Anyone else in the same boat or am I just even more weird?
