Well my dad got Amanda pregnant back in 1992. She was only 2 months pregnant when he left. She met another man. Amanda told Steve when she was 5 months pregnant that he was the father. He believes to this day, that Sarah is his, he believes my half sister, was born premature. Because Sarah was raised by Steve, my dad believes it was never his place/position to intervene and raise her. He's lost contact with Amanda. I grew up without my dad going down that route is a no go, I don't speak to his family either.

A whole year later my dad found out he was the father. All his friends know, that he's the biological dad, and all of Amanda's family and friends know this to.

In 1994 I was born. Up until around 4, I was able to see my sister. We got really close. Her mum stopped me seeing her, because she believed that Steve, would put two and two together. My sister, believes that Steve is her biological father.

When I used to see Sarah, her mum used to take pictures of me and her, and never me, Sarah and her maternal half sister. The problem is she doesn't know I exist, I haven't seen her since we were children. I don't know if her mum will ever tell her the truth.

I added Amanda on a facebook a few years back, and she quickly shut me down and blocked me, when I brought up Sarah. My mum has always said my sister looks like (Lorna) my dad's mother, she's the spitting image of my dad. I haven't seen Sarah in 16 years. She's almost 23, where both officially adults. Before I moved out of London I lived a short distance from her, I don't have her number or address...

It's something that will always niggle at me, because I know Sarah wont look for me. I know Sarah doesn't have any social websites, but her sister does... Do I unload everything onto her... I don't want to be selfish and completely rock that family, but I deserve to know my sister. She has every right to reject me, because she is the innocent party.

What do I do??
