All the people take me too much for granted

I have no idea why all the people take me too much for granted. starting from my parents to my friends. Is it because i love them, care for them? or  sesitive people are considered as fools in this world? no matter how badly they behave with me i always respect them and stnd by them.  i expect nothing more from them other than love, care and respect. everybody asks me to ignore whoever is hurting me. but how can i, when they are my own people?
