I think it just depends on multiple factors. Each relationship is different and each individual has his or her own idiosyncrasies which may become intolerable to the other over time. This is where super heady chicks got a leg up on other girls. My girl's super heady,we've had our issues and moved past them,now she's into the garden and into the beauty of it....Mind you this was a dating situation that led to a relationship where we live with a garden together.
