For having brought you up without much support and acceptance from your father. It is she who is more deserving of your love, duty and companionship.Your father obviously doesn't want you and has no value for you. Why then do you want to pursue him? What do you wish to achieve? From what I hear cases like your's are more often than not abandoned and not heeded hence you may very well be wasting much time, resources and efforts in vain.
Alhamdulillah you are still young and capable of building your own life, free of depending on a man who has no need or love for you.
May Allah grant you much ease and success brother..Aameen!
