What do you make of this situation?

I run a gym and my buddy runs a gym in another country. One of my female clients who had been at my gym for a couple years moved to that country and Went to my friends gym for about a year. She abruptly quit his gym while she was still living in the country. She moved back to my country and back to my gym. When I asked her why she left my buddies gym she said there was a lot of drama. When I ask my buddy he says that his coaches complain that she gets mad when they give attention to other women in class. I’ve never seen her do this at my gym. I’ve tried giving attention to others and she could care less.
