Is it true women don't want to marry a guy that is good to them?

Seen friends have good relationships and then out of no where the woman just says they want to break up, because of things like he treats her too nicely, or he's too good for her, or something like that. From my perspective id love to marry a woman that is good to me. But why don't some women want to marry a guy that genuinely is good to them supportive and caring?
