I wan't to see my dad? anyone help?...?

ok so this is the whole story. my mom and real dad were not actually married. they were only live-in partners, well before! now my dad left for the u.s.a. and broke up with my mom. i never saw him since i was born but here in our country even if the parents are not married if the father take and considers their child as his own child he will allow the child to utilize or use his surname. and that's exactly what happened to me. infact he is my Godfather too. my godfather at my baptismal.the fact that he allowed me to use his surname was a good proof that he reecognizes me as his child.isn't it? the only problem was, he has his real and legal family at new jersey usa now. i wan't to find him hoestly speaking we're having financial problems especially when it comes to my education fees and expenses. he does not send any money for my mom and i because he's not aware of what's hapenning to us. i'ts been years since we don't communicate with one anther.now i wnt to see him bec i miss him too
