If someone keeps getting divorced, would you assume THEY’RE the problem, or they just have bad taste in partners?

Just wondering what everyone thinks about this topic. My aunt for example has been divorced 4 times. She’s really hard to live with and very dramatic and depressive. I’ve always thought to myself that she’s unpleasant and probably the reason for all her divorces. I know another woman who’s my age, only 32, and has been divorced twice and is already with another man. She has a whole bunch of kids too. She’s always been quite nice but so have her husbands. Her first was a nurse and her second was a pediatric dentist. Very nice men. So to me I think she’s probably the problem in some way.
