Could Doris Day have legitimately suffered from a personality disorder?

To give you a better idea of what I mean:

"At her home in Carmel-by-the-Sea, California, she kept many dogs and cats, some of them former strays. Her fourth husband, Barry Comden, whom she married in 1976, complained that the main reason the marriage broke up in 1981 was because she cared for her animals more than him."

She could be the exception, but it's my experience that people who marry so many times have something wrong with them. Often a personality disorder. To screw up that much, she either didn't pay attention to the guy's personality (because she was in it for herself - wanting a husband as an accessory or something like that) and that's a symptom of narcissism (or borderline) -- or she was on the dumb side, like an autistic person, unable to really understand another person very well.

She was friends with Rock Hudson (and loyal to him) so there's that. I'd be interested in knowing if she had other friends who were truly close to her - or if she just stuck to her dogs and cats.
