What’s sh?

For those of you who are wondering what “Sh” means in my posts, it’s short for “Sweetheart”. We used to call each other by no other name, as cliche as it sounds. We could convey exactly what we were feeling at the moment in just that one word. That word meant a lot of things. We would be fighting and still, our sentences would begin and end with sweetheart. In our chats, since it is a long word, we started using “sh”. I am not used to calling him anything else and it feels awkward to use “Ranga”, “Sriranga”, “my husband”, etc. in these posts.
