Well, my half sister is in her 40s... She's never once tried to reach out to my dad for anything other than money.. When she was 16, she chose to abandon not just my dad, but our entire family. She severed all contact with her aunts and uncles and grandparents in our family.

And now she wants my dad to explain why he left her?!

She sent a private message to my mom through Facebook, so it's not being shared with all of our friends.

She puts blame on me and my mom for her mom and my dad never getting together. I think she was always resentful for being a one-night stand baby... But that doesn't change the fact that she chose to believe her mother's lies about my dad and she chose to sever contact with my dad's family.

She admitted herself in her message to my mom that, "he was a great dad", so I don't understand why she is feeling the need to attack my mom for [my half sister's] lack of correspondence with my dad.

I wrote her a message, but haven't sent it yet.

I'm just very upset that she waited soooo long to say anything. When I was born and when we lived in another state, my half sister never said a word. She'd literally only call my dad to ask for money. She even wrote on Facebook that, "[her] son was the only man in the "family" to take care of their kids"... Which, is a lie because my grandfather (whom she stopped talking to) raised his kids well, my uncle also was there for his children from infancy and STILL continues to provide for them even though they are well into their 30s. Even my own dad, whom she said herself, "was a great dad" has been there for her. He would have had custody of her, but she chose to live with her mother and sever ties with our family.

I know that she's very passive aggressive and that really pisses me off. My mom has nothing to do with her and my father's relationship. She was old enough to make a decision to stay in contact with the family and she chose not to. That's no one's fault but her own...
