He called me “Bitch”

I was at the dentist today and suddenly my friend in the msgs called me “Bitch”

I WAS SO SHOCKED!

And in our language the word “bitch” it’s really bad.... like it’s really heavy! It’s more like a whore...

I felt so upset from him.. really.. I don’t like anyone to call me bitch.. it was a normal conversation...

I don’t know how I feel towards him now... unpleasant feeling.
