Family over girlfriend always?

OK I have this boyfriend and it's like every chance he gets he puts his family over me which is fine understandable but at the same time is there a point where that becomes too much? Like if we make plans somehow they always get changed cause he had to go do something for his aunt or uncle like if you are married do you believe in you didn't marry your family you married me? So my question is do you think he is doing the right thing by always putting his family over me or do you think sometimes it's ok but not all the time cause it got to the point that whenever we make plans his family always calls him while he is with me to do something.
