Bio Dad

This isn't really suppose to be in this category but I would really like some other point of views in this because I'm alone.
 When I turned 13, I was told the father that has raised me, was not my father. My brother and me both have the same biological Dad. My brother lives with him and I live with my Dad. My biological Dad said he wanted nothing to do with me when he found out that my Mom was pregnant with me.. But that was 16 years ago. When my Mother and him split up, he rewedded and had 3 more kids. I have a " sister " who is a year younger than me..
 So I have a couple of questions that I have been trying to answer for 3 years now.
Should I try to talk to him? Just so my mind can set to ease?
Do you think he's ever thought about me?
It is still, to this day, hard to wrap my finger around ... PLEASE HELP!
