getting along with people has nothing to do with being close. Sure it's something that has to happen to be close but it does not necessarily require that what follows is closeness. you can be cordial and friendly and respectful to many people but that does in no way say that you are close to them. I get along with all of my coworkers in my job but I am close to none of them. Other than family ties and such there is no difference, they are just other people we are connected to in some way. Nothing odd about it at all. Besides the fact that as families grow, they go their own directions, socialize in different circles and have many times, completely different lifestyles and this is, as it should be. I find that close extended families to be the exception, not the rule in most cases.
