My crush calls me bro?

OK, so added context: in our culture men would have a formal term for women and call them “sisters”. This is because we are religious, so men, including him will refer to other women in the faith as sisters. Only thing is, he calls me bro knowing that I’m a “sister”. He’s this influencer I’ve gotten to know online and is religious, and we talk privately sometimes but I dunno about him calling me bro. How should I feel about it?
