Why should I cross the ocean for you; when you won't even cross the street for me....
Being taken for granted is never a good thing, because this means that you are not appreciated or valued as a person. When you care about someone then it is important that you voice your appreciation for their efforts and support, and that you do not take their presence for granted in your life. Usually being taken for granted makes you feel like you are not important to the person and this is not a nice feeling to have.
